\frac{7}{4}x-1=54\times \frac{1}{2}
Combine x and \frac{3}{4}x to get \frac{7}{4}x.
\frac{7}{4}x-1=\frac{54}{2}
Multiply 54 and \frac{1}{2} to get \frac{54}{2}.
\frac{7}{4}x-1=27
Divide 54 by 2 to get 27.
\frac{7}{4}x=27+1
Add 1 to both sides.
\frac{7}{4}x=28
Add 27 and 1 to get 28.
x=28\times \frac{4}{7}
Multiply both sides by \frac{4}{7}, the reciprocal of \frac{7}{4}.
x=\frac{28\times 4}{7}
Express 28\times \frac{4}{7} as a single fraction.
x=\frac{112}{7}
Multiply 28 and 4 to get 112.
x=16
Divide 112 by 7 to get 16.
