8+y=\frac{90}{-4}
Divide both sides by -4.
8+y=-\frac{45}{2}
Reduce the fraction \frac{90}{-4} to lowest terms by extracting and canceling out 2.
y=-\frac{45}{2}-8
Subtract 8 from both sides.
y=-\frac{45}{2}-\frac{16}{2}
Convert 8 to fraction \frac{16}{2}.
y=\frac{-45-16}{2}
Since -\frac{45}{2} and \frac{16}{2} have the same denominator, subtract them by subtracting their numerators.
y=-\frac{61}{2}
Subtract 16 from -45 to get -61.
