You can solve any proportion using the fundamental rule of proportions. First you must build the proportion if you are given a word problem. Decide using logic whether it is a direct proportion (more on one side means more on the other). If so, find the parts of the equation that use the same units and make a fraction with these, putting the smaller number on top. The number left over is linked with one of the other two numbers in the fraction--use logic to figure out which. Put it in the sam...
This video describes how to solve direct proportions in algebra which is an important and useful skill in everyday life, school and at work. In this video one would learn key elements of a direct proportion and learn to separate them into a more means more or less means less types of proportion. For example if one had a direct proportion of the more means more type one would simply gather the logical numbers and follow the two simple rules for solving. Overall this video is simple and useful ...
In this tutorial the instructor shows how to solve ratios and proportions. He gives a two step approach to solve an equality of two fractions in which the value of a variable in unknown. He says that in the first step we should cross multiply the numbers across the diagonal. In the second step we need to divide and simplify to get the value of the unknown variable. This video gives a simple two step method on how to solve ratios and proportions.
A video from The Free Math Tutor that shows you how to use graphs to solve simple linear algebraically problems in mathematics. This video is introductory in nature and teaches the viewer, proper plotting methods on graphs. The presenter also teaches you how to choose a proper scale for solving such problems.

In this video tutorial the instructor shows how to solve equations by the comparison method. In this method he isolates either the x or y variables in both the equations and now compares the other side of equations directly to derive the value of the other variable. Now this derived value of the variable can be used by substituting it in one of the original variables to derive the value of the other variable. He goes on and shows how to do this with an example by solving it. This video gives ...

In this video the tutor shows how to add/subtract to solve equations. He says that when we are trying to solve simple equations we need to perform the same operation on both the sides of the equation i.e. if we are adding something on one side of the equation we need to add the same thing on the other side of the equation too. Similarly for the subtraction too. He says that by doing this we still maintain the equality of the equation. He shows how to do this with an example. This video gives ...

Math can be tricky, especially when you're trying to decipher algebra. It's a love-hate thing; if you don't love math, then you hate it, and there's no in-between. But it doesn't have to be a pain to solve a few problems. It's actually quite simple once you figure it out. An algebraic equation is an equation that includes one or more variables. These equations can be solved as long as the number of variables does not exceed the number of equations.
While the easiest way to get out of the room in Antrim Escape is the 'Emma' exit, there is another secret method to escape called 'Ethel.' This tutorial shows you how to use the Ethel method to solve Antrim Escape.
Solving 6 math problems using different methods is the idea behind this video. First, you make three rows of numbers vertically from 1-9. All the numbers match across for example, 1 1 1, 2 2 2, 3 3 3, and so on. Each set of numbers creates a mathematical problem who's solution is the number six. These problems require some thinking to solve. The only one that is immediately apparent is 2 2 2=6 which is, of course, 2+2+2=6, (3x3)-3=6, the square root of 4 =2. This done on all three of the four...

Who needs to watch the new "Iron Man" movie when you can solve linear equations? Brush up on your x's and y'x with this video, which teaches you how to solver a linear equation.
This video shows the method to solve a pair of linear equations by plotting their graph. Look for points of intersection of the two graphs which is the solution. Let us solve 5x-y=6 and 2x+y=8. Writing the equations of lines in slope intercept form, we get y=5x-6 and y=-2x+8. Now we plot the two lines. For the slope 5 or 5/1, we go up 5 units and left 1 units from the point of intersection on the y axis. For -2 or -2/1, we go down 2 units and left 1 units from the point of intersection on the...
