5\times 5x-6\left(1-3x\right)=30x-2\left(x-7\right)-30
Multiply both sides of the equation by 30, the least common multiple of 6,5,15.
25x-6\left(1-3x\right)=30x-2\left(x-7\right)-30
Multiply 5 and 5 to get 25.
25x-6+18x=30x-2\left(x-7\right)-30
Use the distributive property to multiply -6 by 1-3x.
43x-6=30x-2\left(x-7\right)-30
Combine 25x and 18x to get 43x.
43x-6=30x-2x+14-30
Use the distributive property to multiply -2 by x-7.
43x-6=28x+14-30
Combine 30x and -2x to get 28x.
43x-6=28x-16
Subtract 30 from 14 to get -16.
43x-6-28x=-16
Subtract 28x from both sides.
15x-6=-16
Combine 43x and -28x to get 15x.
15x=-16+6
Add 6 to both sides.
15x=-10
Add -16 and 6 to get -10.
x=\frac{-10}{15}
Divide both sides by 15.
x=-\frac{2}{3}
Reduce the fraction \frac{-10}{15} to lowest terms by extracting and canceling out 5.
