8\times 70=5S
Variable S cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 8S, the least common multiple of S,8.
560=5S
Multiply 8 and 70 to get 560.
5S=560
Swap sides so that all variable terms are on the left hand side.
S=\frac{560}{5}
Divide both sides by 5.
S=112
Divide 560 by 5 to get 112.
