Question

-11w + 7 + 10w = 19 + 2W
What does the variable W equal?

Answer 1

1. Gather like terms
-w + 7 = 19 + 2
2. Move terms
-w -2w = 19 - 7
3. Subtract
-3w = 12
4. Divide both sides by -3
w = -4

Answer 2

w = -4

Explanation:

-11w + 7 + 10w = 19 + 2w

-1w + 7 = 19 + 2w

-1w + 1w + 7 = 19 + 2w + 1w

7 = 19 + 3w

7 - 19 = 19 - 19 + 3w

-12 = 3w

`(-12)/(3) = (3w)/(3)`

-4 = w
