3\times 25+3x\left(-7\right)+3x\times \frac{5}{3}=3x\times 24-3
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x, the least common multiple of x,3.
75+3x\left(-7\right)+3x\times \frac{5}{3}=3x\times 24-3
Multiply 3 and 25 to get 75.
75-21x+3x\times \frac{5}{3}=3x\times 24-3
Multiply 3 and -7 to get -21.
75-21x+5x=3x\times 24-3
Cancel out 3 and 3.
75-16x=3x\times 24-3
Combine -21x and 5x to get -16x.
75-16x=72x-3
Multiply 3 and 24 to get 72.
75-16x-72x=-3
Subtract 72x from both sides.
75-88x=-3
Combine -16x and -72x to get -88x.
-88x=-3-75
Subtract 75 from both sides.
-88x=-78
Subtract 75 from -3 to get -78.
x=\frac{-78}{-88}
Divide both sides by -88.
x=\frac{39}{44}
Reduce the fraction \frac{-78}{-88} to lowest terms by extracting and canceling out -2.
