y=8+\frac{3\left(-34+10y\right)}{7}
Express 3\times \frac{-34+10y}{7} as a single fraction.
y=8+\frac{-102+30y}{7}
Use the distributive property to multiply 3 by -34+10y.
y=8-\frac{102}{7}+\frac{30}{7}y
Divide each term of -102+30y by 7 to get -\frac{102}{7}+\frac{30}{7}y.
y=\frac{56}{7}-\frac{102}{7}+\frac{30}{7}y
Convert 8 to fraction \frac{56}{7}.
y=\frac{56-102}{7}+\frac{30}{7}y
Since \frac{56}{7} and \frac{102}{7} have the same denominator, subtract them by subtracting their numerators.
y=-\frac{46}{7}+\frac{30}{7}y
Subtract 102 from 56 to get -46.
y-\frac{30}{7}y=-\frac{46}{7}
Subtract \frac{30}{7}y from both sides.
-\frac{23}{7}y=-\frac{46}{7}
Combine y and -\frac{30}{7}y to get -\frac{23}{7}y.
y=-\frac{46}{7}\left(-\frac{7}{23}\right)
Multiply both sides by -\frac{7}{23}, the reciprocal of -\frac{23}{7}.
y=\frac{-46\left(-7\right)}{7\times 23}
Multiply -\frac{46}{7} times -\frac{7}{23} by multiplying numerator times numerator and denominator times denominator.
y=\frac{322}{161}
Do the multiplications in the fraction \frac{-46\left(-7\right)}{7\times 23}.
y=2
Divide 322 by 161 to get 2.
