2y=2-\frac{27}{2}
Subtract \frac{27}{2} from both sides.
2y=\frac{4}{2}-\frac{27}{2}
Convert 2 to fraction \frac{4}{2}.
2y=\frac{4-27}{2}
Since \frac{4}{2} and \frac{27}{2} have the same denominator, subtract them by subtracting their numerators.
2y=-\frac{23}{2}
Subtract 27 from 4 to get -23.
y=\frac{-\frac{23}{2}}{2}
Divide both sides by 2.
y=\frac{-23}{2\times 2}
Express \frac{-\frac{23}{2}}{2} as a single fraction.
y=\frac{-23}{4}
Multiply 2 and 2 to get 4.
y=-\frac{23}{4}
Fraction \frac{-23}{4} can be rewritten as -\frac{23}{4} by extracting the negative sign.
