Answer: x=20
Step-by-step explanation:
The entire thing is equal to 180 degrees. so, 100+3x+x=180, which can be simplified to 100+4x=180. If we subtract 100 from both sides, we get 4x=80, 80 divided by 4 is 20, so x=20
Subtract 4x on both sides then divide by negative to all three numbers and your answer will be y = 1/2x - 3/2
