\frac{10\times 8}{1\times 8+7}=8x-2x+x-3x
Divide 10 by \frac{1\times 8+7}{8} by multiplying 10 by the reciprocal of \frac{1\times 8+7}{8}.
\frac{80}{1\times 8+7}=8x-2x+x-3x
Multiply 10 and 8 to get 80.
\frac{80}{8+7}=8x-2x+x-3x
Multiply 1 and 8 to get 8.
\frac{80}{15}=8x-2x+x-3x
Add 8 and 7 to get 15.
\frac{16}{3}=8x-2x+x-3x
Reduce the fraction \frac{80}{15} to lowest terms by extracting and canceling out 5.
\frac{16}{3}=6x+x-3x
Combine 8x and -2x to get 6x.
\frac{16}{3}=7x-3x
Combine 6x and x to get 7x.
\frac{16}{3}=4x
Combine 7x and -3x to get 4x.
4x=\frac{16}{3}
Swap sides so that all variable terms are on the left hand side.
x=\frac{\frac{16}{3}}{4}
Divide both sides by 4.
x=\frac{16}{3\times 4}
Express \frac{\frac{16}{3}}{4} as a single fraction.
x=\frac{16}{12}
Multiply 3 and 4 to get 12.
x=\frac{4}{3}
Reduce the fraction \frac{16}{12} to lowest terms by extracting and canceling out 4.
