10-1=\left(\frac{1}{21}x-\frac{1}{21}\right)\left(50-4\right)
Variable x cannot be equal to 1 since division by zero is not defined. Multiply both sides of the equation by x-1.
9=\left(\frac{1}{21}x-\frac{1}{21}\right)\left(50-4\right)
Subtract 1 from 10 to get 9.
9=\left(\frac{1}{21}x-\frac{1}{21}\right)\times 46
Subtract 4 from 50 to get 46.
9=\frac{46}{21}x-\frac{46}{21}
Use the distributive property to multiply \frac{1}{21}x-\frac{1}{21} by 46.
\frac{46}{21}x-\frac{46}{21}=9
Swap sides so that all variable terms are on the left hand side.
\frac{46}{21}x=9+\frac{46}{21}
Add \frac{46}{21} to both sides.
\frac{46}{21}x=\frac{235}{21}
Add 9 and \frac{46}{21} to get \frac{235}{21}.
x=\frac{235}{21}\times \frac{21}{46}
Multiply both sides by \frac{21}{46}, the reciprocal of \frac{46}{21}.
x=\frac{235}{46}
Multiply \frac{235}{21} and \frac{21}{46} to get \frac{235}{46}.
