When solving the equation -1/2 ( x + 10 ) = 3, identify the operation that should be done at first.

Question

Add 10

divide by -2

Multiply by -2

Subtract 10

Answer 1

To solve the equation \(-\frac{1}{2} (x + 10) = 3\), the first operation that should be done is to eliminate the -1/2 coefficient. The operation to do this is to multiply both sides of the equation by -2.

Therefore, the correct answer is: Multiply by -2.
