Answer:
x=−y+1
Step-by-step explanation:
Let's solve for x.
4x+4y=4
Step 1: Add -4y to both sides.
4x+4y+−4y=4+−4y
4x=−4y+4
Step 2: Divide both sides by 4.
<u>4x </u> = <u>−4y+4</u>
4 = 4
x=−y+1

Answer:
E. C. D
Step-by-step explanation:
Thoae are the corrwct ones, hope ir helpa :)
Let the "other" angle be x. Then we can set up the equation: 2x + 60 + x = 180, because supplementary means that the angles add up to 180 degrees.
We get:
3x + 60 = 180
3x = 120
x = 40.
2(40) + 60 = 80 + 60 = 140.
So one angle is 140 degrees and the other angle is 40 degrees.
