7\times 4=8x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 7x, the least common multiple of x,7.
28=8x
Multiply 7 and 4 to get 28.
8x=28
Swap sides so that all variable terms are on the left hand side.
x=\frac{28}{8}
Divide both sides by 8.
x=\frac{7}{2}
Reduce the fraction \frac{28}{8} to lowest terms by extracting and canceling out 4.
