Answer:
Multiplication
Explanation:
A coefficient is a number that sits in front of a variable, like this: 3x. It means that you're going to multiply 3 times x, or that there are 3 x's. You may be given an equation that looks like this: 3x = 12. In this case, you're going to divide each “side” of the equation by the coefficient of x (3, in our example).
