1-\frac{2}{7}x=49
Divide 9 by 9 to get 1.
-\frac{2}{7}x=49-1
Subtract 1 from both sides.
-\frac{2}{7}x=48
Subtract 1 from 49 to get 48.
x=48\left(-\frac{7}{2}\right)
Multiply both sides by -\frac{7}{2}, the reciprocal of -\frac{2}{7}.
x=\frac{48\left(-7\right)}{2}
Express 48\left(-\frac{7}{2}\right) as a single fraction.
x=\frac{-336}{2}
Multiply 48 and -7 to get -336.
x=-168
Divide -336 by 2 to get -168.
