3\left(6x+1\right)-7\left(2x-7\right)=84
Multiply both sides of the equation by 21, the least common multiple of 7,3.
18x+3-7\left(2x-7\right)=84
Use the distributive property to multiply 3 by 6x+1.
18x+3-14x+49=84
Use the distributive property to multiply -7 by 2x-7.
4x+3+49=84
Combine 18x and -14x to get 4x.
4x+52=84
Add 3 and 49 to get 52.
4x=84-52
Subtract 52 from both sides.
4x=32
Subtract 52 from 84 to get 32.
x=\frac{32}{4}
Divide both sides by 4.
x=8
Divide 32 by 4 to get 8.
