42y-3\left(4\times 14+5\right)=-2\left(5\times 21+11\right)
Multiply both sides of the equation by 42, the least common multiple of 14,21.
42y-3\left(56+5\right)=-2\left(5\times 21+11\right)
Multiply 4 and 14 to get 56.
42y-3\times 61=-2\left(5\times 21+11\right)
Add 56 and 5 to get 61.
42y-183=-2\left(5\times 21+11\right)
Multiply -3 and 61 to get -183.
42y-183=-2\left(105+11\right)
Multiply 5 and 21 to get 105.
42y-183=-2\times 116
Add 105 and 11 to get 116.
42y-183=-232
Multiply -2 and 116 to get -232.
42y=-232+183
Add 183 to both sides.
42y=-49
Add -232 and 183 to get -49.
y=\frac{-49}{42}
Divide both sides by 42.
y=-\frac{7}{6}
Reduce the fraction \frac{-49}{42} to lowest terms by extracting and canceling out 7.
