Here's how we solve a two step equation. It begins with the concept of equality: what we do to one side of the equation must be done to the other.
Amadou, If you are asking how you would solve such an equation, then here is what you would do. Remember that the equals sign means that everything on the left side is the same as everything on the right side. The two sides are equal, or balanced. So as long as you do the same thing to both sides, they STAY balanced.
Practice solving equations that take two steps to solve. For example, solve -16 = x /4 + 2.

It takes two steps to solve an equation or inequality that has more than one operation: Simplify using the inverse of addition or subtraction. Simplify further by using the inverse of multiplication or division. Remember, when you multiply or divide an inequality by a negative number, you must reverse the inequality symbol.

A two-step equation is as straightforward as it sounds. You will need to perform two steps in order to solve the equation. One goal in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other goal is to have the number in front of the variable equal to ...
