Answer: =80/11
Step-by-step explanation:x=80-10x
We move all terms to the left:
x-(80-10x)=0
We add all the numbers together, and all the variables
x-(-10x+80)=0
We get rid of parentheses
x+10x-80=0
We add all the numbers together, and all the variables
11x-80=0
We move all terms containing x to the left, all other terms to the right
11x=80
x=80/11
x=7+3/11
