Please help me i’m confused

Your answer is 3.

You wanna multiply both sides of the equation by 5

2w - 1 + 5w + 10 = 10w

Combine the 2w and 5w and you should get 7w

7w - 1 + 10 = 10w

Add -1 and 10 to get 9

7w + 9 = 10

Subtract 10w from both sides

7w + 9 - 10w = 0

Combine 7w and -10w to get -3w
-3w + 9 = 0

Subtract 9 from both sides. Anything subtracted from zero gives its negation

-3w = -9

Divide them

W= -9/-3

3 \ 9 = 3

W= 3
