x=\frac{3}{4}x+\frac{1}{7}x+3
Combine \frac{1}{2}x and \frac{1}{4}x to get \frac{3}{4}x.
x=\frac{25}{28}x+3
Combine \frac{3}{4}x and \frac{1}{7}x to get \frac{25}{28}x.
x-\frac{25}{28}x=3
Subtract \frac{25}{28}x from both sides.
\frac{3}{28}x=3
Combine x and -\frac{25}{28}x to get \frac{3}{28}x.
x=3\times \frac{28}{3}
Multiply both sides by \frac{28}{3}, the reciprocal of \frac{3}{28}.
x=28
Cancel out 3 and 3.
