3\times 10=7x
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.
30=7x
Multiply 3 and 10 to get 30.
7x=30
Swap sides so that all variable terms are on the left hand side.
x=\frac{30}{7}
Divide both sides by 7.
