36+4\left(4x-1\right)=3\left(5x+7\right)+12x
Multiply both sides of the equation by 12, the least common multiple of 3,4.
36+16x-4=3\left(5x+7\right)+12x
Use the distributive property to multiply 4 by 4x-1.
32+16x=3\left(5x+7\right)+12x
Subtract 4 from 36 to get 32.
32+16x=15x+21+12x
Use the distributive property to multiply 3 by 5x+7.
32+16x=27x+21
Combine 15x and 12x to get 27x.
32+16x-27x=21
Subtract 27x from both sides.
32-11x=21
Combine 16x and -27x to get -11x.
-11x=21-32
Subtract 32 from both sides.
-11x=-11
Subtract 32 from 21 to get -11.
x=\frac{-11}{-11}
Divide both sides by -11.
x=1
Divide -11 by -11 to get 1.
