What if there is a number multiplying the x? In this case, you will divide both sides of the equation by that number. To solve , divide both sides by 5 to get . As before, perform the opposite operation to both sides.

It is possible to have to do both of these steps or to even move variables in this way as you can see in the examples below.

Solving Quadratic Equations

Quadratic equations are equations that contain the square of a variable such as . or Many quadratics can be written as , where b and c are numbers. In this case, they can be solved just by factoring and then setting each term to zero. When you do this, you end up with two linear equations that can be solved in the way we just discussed. Here are some examples:
