2\left(4x-7\right)-30x-66=3\left(x-1\right)
Multiply both sides of the equation by 6, the least common multiple of 3,2.
8x-14-30x-66=3\left(x-1\right)
Use the distributive property to multiply 2 by 4x-7.
-22x-14-66=3\left(x-1\right)
Combine 8x and -30x to get -22x.
-22x-80=3\left(x-1\right)
Subtract 66 from -14 to get -80.
-22x-80=3x-3
Use the distributive property to multiply 3 by x-1.
-22x-80-3x=-3
Subtract 3x from both sides.
-25x-80=-3
Combine -22x and -3x to get -25x.
-25x=-3+80
Add 80 to both sides.
-25x=77
Add -3 and 80 to get 77.
x=\frac{77}{-25}
Divide both sides by -25.
x=-\frac{77}{25}
Fraction \frac{77}{-25} can be rewritten as -\frac{77}{25} by extracting the negative sign.
