12+3\left(7-x\right)+21-9\left(x+1\right)=4\left(1-x\right)+33
Multiply both sides of the equation by 18, the least common multiple of 3,6,2,9.
12+21-3x+21-9\left(x+1\right)=4\left(1-x\right)+33
Use the distributive property to multiply 3 by 7-x.
33-3x+21-9\left(x+1\right)=4\left(1-x\right)+33
Add 12 and 21 to get 33.
54-3x-9\left(x+1\right)=4\left(1-x\right)+33
Add 33 and 21 to get 54.
54-3x-9x-9=4\left(1-x\right)+33
Use the distributive property to multiply -9 by x+1.
54-12x-9=4\left(1-x\right)+33
Combine -3x and -9x to get -12x.
45-12x=4\left(1-x\right)+33
Subtract 9 from 54 to get 45.
45-12x=4-4x+33
Use the distributive property to multiply 4 by 1-x.
45-12x=37-4x
Add 4 and 33 to get 37.
45-12x+4x=37
Add 4x to both sides.
45-8x=37
Combine -12x and 4x to get -8x.
-8x=37-45
Subtract 45 from both sides.
-8x=-8
Subtract 45 from 37 to get -8.
x=\frac{-8}{-8}
Divide both sides by -8.
x=1
Divide -8 by -8 to get 1.
