Answer: 25 (i think)
Step-by-step explanation:
Simplifying
7w + -9 = 13 + -4w
Reorder the terms:
-9 + 7w = 13 + -4w
Solving
-9 + 7w = 13 + -4w
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '4w' to each side of the equation.
-9 + 7w + 4w = 13 + -4w + 4w
Combine like terms: 7w + 4w = 11w
-9 + 11w = 13 + -4w + 4w
Combine like terms: -4w + 4w = 0
-9 + 11w = 13 + 0
-9 + 11w = 13
Add '9' to each side of the equation.
-9 + 9 + 11w = 13 + 9
Combine like terms: -9 + 9 = 0
0 + 11w = 13 + 9
11w = 13 + 9
Combine like terms: 13 + 9 = 22
11w = 22
Divide each side by '11'.
w = 2
Simplifying
w = 2
