-6x=\frac{4}{2}\times \frac{49}{16}-\frac{3}{2}-8
Multiply \frac{1}{2} and 4 to get \frac{4}{2}.
-6x=2\times \frac{49}{16}-\frac{3}{2}-8
Divide 4 by 2 to get 2.
-6x=\frac{2\times 49}{16}-\frac{3}{2}-8
Express 2\times \frac{49}{16} as a single fraction.
-6x=\frac{98}{16}-\frac{3}{2}-8
Multiply 2 and 49 to get 98.
-6x=\frac{49}{8}-\frac{3}{2}-8
Reduce the fraction \frac{98}{16} to lowest terms by extracting and canceling out 2.
-6x=\frac{49}{8}-\frac{12}{8}-8
Least common multiple of 8 and 2 is 8. Convert \frac{49}{8} and \frac{3}{2} to fractions with denominator 8.
-6x=\frac{49-12}{8}-8
Since \frac{49}{8} and \frac{12}{8} have the same denominator, subtract them by subtracting their numerators.
-6x=\frac{37}{8}-8
Subtract 12 from 49 to get 37.
-6x=\frac{37}{8}-\frac{64}{8}
Convert 8 to fraction \frac{64}{8}.
-6x=\frac{37-64}{8}
Since \frac{37}{8} and \frac{64}{8} have the same denominator, subtract them by subtracting their numerators.
-6x=-\frac{27}{8}
Subtract 64 from 37 to get -27.
x=\frac{-\frac{27}{8}}{-6}
Divide both sides by -6.
x=\frac{-27}{8\left(-6\right)}
Express \frac{-\frac{27}{8}}{-6} as a single fraction.
x=\frac{-27}{-48}
Multiply 8 and -6 to get -48.
x=\frac{9}{16}
Reduce the fraction \frac{-27}{-48} to lowest terms by extracting and canceling out -3.
