Answer:
x=100
Step-by-step explanation:
(2x+8)+(71-x)=180
2x+8+71-x=180
x+80=180

Answer:
y=5x-10
Step-by-step explanation:
y+10=5x
y=5x-10
1.) you would distribute the 6---- 12x-66+15
2.) you would add like terms---- 12x-51=3x+12
3.) you would subtract 3x from each side of the equal sign---- 9x-51=12
4.) you would add 51 on each side of the equal sign----9x=63
5.) you would divide both sides of the equal sign by 9 giving you you answer--------- x=7
