\frac{2}{5}x-\frac{1}{3}-\frac{4}{15}x=3
Subtract \frac{4}{15}x from both sides.
\frac{2}{15}x-\frac{1}{3}=3
Combine \frac{2}{5}x and -\frac{4}{15}x to get \frac{2}{15}x.
\frac{2}{15}x=3+\frac{1}{3}
Add \frac{1}{3} to both sides.
\frac{2}{15}x=\frac{9}{3}+\frac{1}{3}
Convert 3 to fraction \frac{9}{3}.
\frac{2}{15}x=\frac{9+1}{3}
Since \frac{9}{3} and \frac{1}{3} have the same denominator, add them by adding their numerators.
\frac{2}{15}x=\frac{10}{3}
Add 9 and 1 to get 10.
x=\frac{10}{3}\times \frac{15}{2}
Multiply both sides by \frac{15}{2}, the reciprocal of \frac{2}{15}.
x=\frac{10\times 15}{3\times 2}
Multiply \frac{10}{3} times \frac{15}{2} by multiplying numerator times numerator and denominator times denominator.
x=\frac{150}{6}
Do the multiplications in the fraction \frac{10\times 15}{3\times 2}.
x=25
Divide 150 by 6 to get 25.
