xa\times 2=5a\times 8
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5ax, the least common multiple of a\times 5,x.
xa\times 2=40a
Multiply 5 and 8 to get 40.
2ax=40a
The equation is in standard form.
\frac{2ax}{2a}=\frac{40a}{2a}
Divide both sides by 2a.
x=\frac{40a}{2a}
Dividing by 2a undoes the multiplication by 2a.
x=20
Divide 40a by 2a.
