Question

Which of the following would eliminate the variable on the left side of the given equation?

38 - 15w = 25w + 4

Answer 1

17/20

Explanation:

=> 38 - 15w = 25w + 4

=> -15w - 25w = 4 - 38

=> -40w = -34

=> w = -34/-40

=> w = 17/20

Answer 2

Bring the coefficients to the same side. It doesn't matter which coefficient you choose, but since you asked to remove it from the left, I will bring the -15w to the right. This will also allow you to avoid dealing with negatives.

`88-15w=25w+4`

`38=40w+4`
