Answer:
X=12
Step-by-step explanation:
3(80-9x)=X-96 Distribute 3 through the parenthesis
240-27x=x-96
Move the variable to the left side and change its sign
Move constant to the right side and change its sign
-27x-x+240=-96
collect the like terms
calculate the difference
-28x=-336
Divide both sides of the equation by -28
x=12
