x+\frac{3}{4}x=\frac{28}{2}
Divide both sides by 2.
x+\frac{3}{4}x=14
Divide 28 by 2 to get 14.
\frac{7}{4}x=14
Combine x and \frac{3}{4}x to get \frac{7}{4}x.
x=14\times \frac{4}{7}
Multiply both sides by \frac{4}{7}, the reciprocal of \frac{7}{4}.
x=\frac{14\times 4}{7}
Express 14\times \frac{4}{7} as a single fraction.
x=\frac{56}{7}
Multiply 14 and 4 to get 56.
x=8
Divide 56 by 7 to get 8.
