\frac{1}{5}x+3+\frac{1}{4}x=3
Add \frac{1}{4}x to both sides.
\frac{9}{20}x+3=3
Combine \frac{1}{5}x and \frac{1}{4}x to get \frac{9}{20}x.
\frac{9}{20}x=3-3
Subtract 3 from both sides.
\frac{9}{20}x=0
Subtract 3 from 3 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since \frac{9}{20} is not equal to 0, x must be equal to 0.
