\frac{7\times 6}{3}-\frac{30}{100}x=1.7
Express \frac{7}{3}\times 6 as a single fraction.
\frac{42}{3}-\frac{30}{100}x=1.7
Multiply 7 and 6 to get 42.
14-\frac{30}{100}x=1.7
Divide 42 by 3 to get 14.
14-\frac{3}{10}x=1.7
Reduce the fraction \frac{30}{100} to lowest terms by extracting and canceling out 10.
-\frac{3}{10}x=1.7-14
Subtract 14 from both sides.
-\frac{3}{10}x=-12.3
Subtract 14 from 1.7 to get -12.3.
x=-12.3\left(-\frac{10}{3}\right)
Multiply both sides by -\frac{10}{3}, the reciprocal of -\frac{3}{10}.
x=-\frac{123}{10}\left(-\frac{10}{3}\right)
Convert decimal number -12.3 to fraction -\frac{123}{10}.
x=\frac{-123\left(-10\right)}{10\times 3}
Multiply -\frac{123}{10} times -\frac{10}{3} by multiplying numerator times numerator and denominator times denominator.
x=\frac{1230}{30}
Do the multiplications in the fraction \frac{-123\left(-10\right)}{10\times 3}.
x=41
Divide 1230 by 30 to get 41.
