3\times 6+1=-30x+1\times 6+1
Multiply both sides of the equation by 6.
18+1=-30x+1\times 6+1
Multiply 3 and 6 to get 18.
19=-30x+1\times 6+1
Add 18 and 1 to get 19.
19=-30x+6+1
Multiply 1 and 6 to get 6.
19=-30x+7
Add 6 and 1 to get 7.
-30x+7=19
Swap sides so that all variable terms are on the left hand side.
-30x=19-7
Subtract 7 from both sides.
-30x=12
Subtract 7 from 19 to get 12.
x=\frac{12}{-30}
Divide both sides by -30.
x=-\frac{2}{5}
Reduce the fraction \frac{12}{-30} to lowest terms by extracting and canceling out 6.
