72-7\times 6x=504
Multiply both sides of the equation by 63, the least common multiple of 7,9.
72-42x=504
Multiply -7 and 6 to get -42.
-42x=504-72
Subtract 72 from both sides.
-42x=432
Subtract 72 from 504 to get 432.
x=\frac{432}{-42}
Divide both sides by -42.
x=-\frac{72}{7}
Reduce the fraction \frac{432}{-42} to lowest terms by extracting and canceling out 6.
