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'.
y = 3

Answer:
Step-by-step explanation:
∠1 and 85 are supplementary
m∠1 = 180 - 85 = 95°
