4[2y + -3] + -1 = 11
Reorder the terms:
4[-3 + 2y] + -1 = 11
[-3 * 4 + 2y * 4] + -1 = 11
[-12 + 8y] + -1 = 11
Reorder the terms:
-12 + -1 + 8y = 11
Combine like terms: -12 + -1 = -13
-13 + 8y = 11
Solving
-13 + 8y = 11
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '13' to each side of the equation.
-13 + 13 + 8y = 11 + 13
Combine like terms: -13 + 13 = 0
0 + 8y = 11 + 13
8y = 11 + 13
Combine like terms: 11 + 13 = 24
8y = 24
Divide each side by '8'.

60+ 30w = 480
-60 -60
30w = 420
Divide by 30 on each side
w = 14
Answer:
w=-2
Step-by-step explanation:
9(w-4)-7w=5(3w-2)
9w-36-7w=15w-10
9w-7w-15w=-10+36
-13w=26
w=-2
