2x-4\times 30=140x
Multiply both sides of the equation by 2.
2x-120=140x
Multiply -4 and 30 to get -120.
2x-120-140x=0
Subtract 140x from both sides.
-138x-120=0
Combine 2x and -140x to get -138x.
-138x=120
Add 120 to both sides. Anything plus zero gives itself.
x=\frac{120}{-138}
Divide both sides by -138.
x=-\frac{20}{23}
Reduce the fraction \frac{120}{-138} to lowest terms by extracting and canceling out 6.
