2x-6+3\left(x+7\right)=21
Use the distributive property to multiply 2 by x-3.
2x-6+3x+21=21
Use the distributive property to multiply 3 by x+7.
5x-6+21=21
Combine 2x and 3x to get 5x.
5x+15=21
Add -6 and 21 to get 15.
5x=21-15
Subtract 15 from both sides.
5x=6
Subtract 15 from 21 to get 6.
x=\frac{6}{5}
Divide both sides by 5.
