14\times 4.5=3x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 14x, the least common multiple of x,14.
63=3x
Multiply 14 and 4.5 to get 63.
3x=63
Swap sides so that all variable terms are on the left hand side.
x=\frac{63}{3}
Divide both sides by 3.
x=21
Divide 63 by 3 to get 21.
