xc=20\times 15
Multiply both sides of the equation by 20x, the least common multiple of 20,x.
xc=300
Multiply 20 and 15 to get 300.
\frac{xc}{x}=\frac{300}{x}
Divide both sides by x.
c=\frac{300}{x}
Dividing by x undoes the multiplication by x.
xc=20\times 15
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 20x, the least common multiple of 20,x.
xc=300
Multiply 20 and 15 to get 300.
cx=300
The equation is in standard form.
\frac{cx}{c}=\frac{300}{c}
Divide both sides by c.
x=\frac{300}{c}
Dividing by c undoes the multiplication by c.
x=\frac{300}{c}\text{, }x\neq 0
Variable x cannot be equal to 0.
