Answer:
x=30
Step-by-step explanation:
The two angles are supplementary. They add to 180
4x+20 + 40 =180
Combine like terms
4x+60 =180
Subtract 60 from each side
4x+60-60 = 180-60
4x = 120
Divide each side by 4
4x/4 = 120/4
x = 30
Y + 4 = 2(x - 1)
y + 4 = 2x - 2
-2x + y = -2 - 4 = -6
-2x + y = -6
The correct answer is 40,300. Hope this helps. Please mark as brainliest.
