Question

Which steps can be used to solve for the value of y?

2/3 (y+57)=178

A. Divide both sides by 2/3, then subtract 57 from both sides.

B. Subtract 57 from both sides, then divide both sides by 2/3.

C. Multiply both sides by 2/3, then subtract 57 from both sides.

D. Subtract 2/3 from both sides, then subtract 57 from both sides.

Answer 1

A. Divide both sides by 2/3, then subtract 57 from both sides.

Explanation:

You want to know the steps to solve 2/3(y +57) = 178 for y.

Steps

The variable has 57 added to it, and the sum is multiplied by 2/3. To solve for y, you need to undo these operations in reverse order.

First, you divide by 2/3.

y +57 = 267

Then you subtract 57.

y = 210
