6x+30=10\times \frac{1}{15}
Use the distributive property to multiply 6 by x+5.
6x+30=\frac{10}{15}
Multiply 10 and \frac{1}{15} to get \frac{10}{15}.
6x+30=\frac{2}{3}
Reduce the fraction \frac{10}{15} to lowest terms by extracting and canceling out 5.
6x=\frac{2}{3}-30
Subtract 30 from both sides.
6x=\frac{2}{3}-\frac{90}{3}
Convert 30 to fraction \frac{90}{3}.
6x=\frac{2-90}{3}
Since \frac{2}{3} and \frac{90}{3} have the same denominator, subtract them by subtracting their numerators.
6x=-\frac{88}{3}
Subtract 90 from 2 to get -88.
x=\frac{-\frac{88}{3}}{6}
Divide both sides by 6.
x=\frac{-88}{3\times 6}
Express \frac{-\frac{88}{3}}{6} as a single fraction.
x=\frac{-88}{18}
Multiply 3 and 6 to get 18.
x=-\frac{44}{9}
Reduce the fraction \frac{-88}{18} to lowest terms by extracting and canceling out 2.
