-6+3x+3\left(x+6\right)=10-4\left(6+4x\right)
Use the distributive property to multiply -3 by 2-x.
-6+3x+3x+18=10-4\left(6+4x\right)
Use the distributive property to multiply 3 by x+6.
-6+6x+18=10-4\left(6+4x\right)
Combine 3x and 3x to get 6x.
12+6x=10-4\left(6+4x\right)
Add -6 and 18 to get 12.
12+6x=10-24-16x
Use the distributive property to multiply -4 by 6+4x.
12+6x=-14-16x
Subtract 24 from 10 to get -14.
12+6x+16x=-14
Add 16x to both sides.
12+22x=-14
Combine 6x and 16x to get 22x.
22x=-14-12
Subtract 12 from both sides.
22x=-26
Subtract 12 from -14 to get -26.
x=\frac{-26}{22}
Divide both sides by 22.
x=-\frac{13}{11}
Reduce the fraction \frac{-26}{22} to lowest terms by extracting and canceling out 2.
