Question

What value of w makes the equation below true 7w - 3w = 2(3w + 11)

Answer 1

w = -11

Explanation:

`7w-3w=2(3w+11)\\4w=6w+22\\-2w=22\\w=-11`

Answer 2

w = -11

Explanation:

7w - 3w = 2(3w + 11)

Combine like terms on the left

4w = 2(3w + 11)

Divide by 2

4/2w = 2/2(3w + 11)

2w =(3w + 11)

Subtract 3w from each side

2w-3w = 3w+11-3w

-w = 11

Multiply by -1

w = -11
