Example Question #17 : One Step Equations With Integers

Solve the following equation:

Possible Answers:

Correct answer:

Explanation:

In order to solve this equation, you have to isolate the variable to one side by reversing the operations done to it. Whatever is done on one side of the equals sign must be done on the other side of the equals sign as well. When the variable is by itself, it will be defined as whatever is left on the other side of the equals sign, and the equation is solved.

Subtract  from each side.
