3\left(4x+7\right)-2\left(6x+3\right)=7x+4+18
Multiply both sides of the equation by 6, the least common multiple of 2,3,6.
12x+21-2\left(6x+3\right)=7x+4+18
Use the distributive property to multiply 3 by 4x+7.
12x+21-12x-6=7x+4+18
Use the distributive property to multiply -2 by 6x+3.
21-6=7x+4+18
Combine 12x and -12x to get 0.
15=7x+4+18
Subtract 6 from 21 to get 15.
15=7x+22
Add 4 and 18 to get 22.
7x+22=15
Swap sides so that all variable terms are on the left hand side.
7x=15-22
Subtract 22 from both sides.
7x=-7
Subtract 22 from 15 to get -7.
x=\frac{-7}{7}
Divide both sides by 7.
x=-1
Divide -7 by 7 to get -1.
