10\times 49=s\times 35
Variable s cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10s, the least common multiple of s,10.
490=s\times 35
Multiply 10 and 49 to get 490.
s\times 35=490
Swap sides so that all variable terms are on the left hand side.
s=\frac{490}{35}
Divide both sides by 35.
s=14
Divide 490 by 35 to get 14.
