Answer: x=1+1/3
Step-by-step explanation: -(3x-12)=9x-4
We move all terms to the left:
-(3x-12)-(9x-4)=0
We get rid of parentheses
-3x-9x+12+4=0
We add all the numbers together, and all the variables
-12x+16=0
We move all terms containing x to the left, all other terms to the right
-12x=-16
x=-16/-12
x=1+1/3
