How To: Solve systems by substitution

You can solve systems by using the substitution method. Here are two examples. One says y=3x+2 and the second says 7x-4y=7. The math teacher explains that if y is the same thing as 3x+2, then 3x+2 can be substituted for y in 7x-4y=7. Once it is substituted, your equation will then read 7x-4(3x+2)=7. The next step is to solve for x. Once you have worked out this equation, you will see that x=-3. Finally, your last step is to solve for y. To solve for y, simply substitute x with -3. The equatio...

How To: Simplify square roots

How To: Do long division with different approaches

Taking equal groups, in our case, 7 out of the whole number, in this case 364 involves guessing. A shorter method involves taking groups, in our case, 7 out of each individual number 3, 6 and 4. If you cannot take 7 out of a number, you will subtract 0 from that number and carry down the next number. For example, you cannot take 7 from 3, so you will subtract 3-0 with the answer being 3 and carry down the next number, 6, giving you 36. You can take 5 groups of 7 out. 5 groups of 7 equals 35, ...

How To: Solve one-step inequalities

The one step inequalities are one of the easiest method in mathematics that you can add or subtracting the values in an equation. Consider the equation M+7=-3(Assume M+7 as left side & -3 as right side), in this you should add -7 on both sides of the equation. In the next step on the left side +7 and -7 get cancel each other and in the right side -3 and -7 will become -10 (since minus multiplied with minus gives minus symbol by adding the values). In the next step value of M=-10, this can be ...
