3x+3\left(x+2x\right)+4+2\left(3\left(x+2x\right)+4\right)=132
Combine x and 2x to get 3x.
3x+3\times 3x+4+2\left(3\left(x+2x\right)+4\right)=132
Combine x and 2x to get 3x.
3x+9x+4+2\left(3\left(x+2x\right)+4\right)=132
Multiply 3 and 3 to get 9.
12x+4+2\left(3\left(x+2x\right)+4\right)=132
Combine 3x and 9x to get 12x.
12x+4+2\left(3\times 3x+4\right)=132
Combine x and 2x to get 3x.
12x+4+2\left(9x+4\right)=132
Multiply 3 and 3 to get 9.
12x+4+18x+8=132
Use the distributive property to multiply 2 by 9x+4.
30x+4+8=132
Combine 12x and 18x to get 30x.
30x+12=132
Add 4 and 8 to get 12.
30x=132-12
Subtract 12 from both sides.
30x=120
Subtract 12 from 132 to get 120.
x=\frac{120}{30}
Divide both sides by 30.
x=4
Divide 120 by 30 to get 4.
