-\frac{5}{2}y+\frac{1}{2}+\frac{2}{5}y=-5
Add \frac{2}{5}y to both sides.
-\frac{21}{10}y+\frac{1}{2}=-5
Combine -\frac{5}{2}y and \frac{2}{5}y to get -\frac{21}{10}y.
-\frac{21}{10}y=-5-\frac{1}{2}
Subtract \frac{1}{2} from both sides.
-\frac{21}{10}y=-\frac{10}{2}-\frac{1}{2}
Convert -5 to fraction -\frac{10}{2}.
-\frac{21}{10}y=\frac{-10-1}{2}
Since -\frac{10}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.
-\frac{21}{10}y=-\frac{11}{2}
Subtract 1 from -10 to get -11.
y=-\frac{11}{2}\left(-\frac{10}{21}\right)
Multiply both sides by -\frac{10}{21}, the reciprocal of -\frac{21}{10}.
y=\frac{-11\left(-10\right)}{2\times 21}
Multiply -\frac{11}{2} times -\frac{10}{21} by multiplying numerator times numerator and denominator times denominator.
y=\frac{110}{42}
Do the multiplications in the fraction \frac{-11\left(-10\right)}{2\times 21}.
y=\frac{55}{21}
Reduce the fraction \frac{110}{42} to lowest terms by extracting and canceling out 2.
