4x+14+2x=x\left(10+2\right)+15-3\left(2x+x\right)
Subtract 6 from 20 to get 14.
6x+14=x\left(10+2\right)+15-3\left(2x+x\right)
Combine 4x and 2x to get 6x.
6x+14=x\times 12+15-3\left(2x+x\right)
Add 10 and 2 to get 12.
6x+14=x\times 12+15-3\times 3x
Combine 2x and x to get 3x.
6x+14=x\times 12+15-9x
Multiply 3 and 3 to get 9.
6x+14=3x+15
Combine x\times 12 and -9x to get 3x.
6x+14-3x=15
Subtract 3x from both sides.
3x+14=15
Combine 6x and -3x to get 3x.
3x=15-14
Subtract 14 from both sides.
3x=1
Subtract 14 from 15 to get 1.
x=\frac{1}{3}
Divide both sides by 3.
