3\left(3+x\right)-4x=60
Multiply both sides of the equation by 12, the least common multiple of 4,3.
9+3x-4x=60
Use the distributive property to multiply 3 by 3+x.
9-x=60
Combine 3x and -4x to get -x.
-x=60-9
Subtract 9 from both sides.
-x=51
Subtract 9 from 60 to get 51.
x=-51
Multiply both sides by -1.
