5-2y=-14
Multiply 5 and 1 to get 5.
-2y=-14-5
Subtract 5 from both sides.
-2y=-19
Subtract 5 from -14 to get -19.
y=\frac{-19}{-2}
Divide both sides by -2.
y=\frac{19}{2}
Fraction \frac{-19}{-2} can be simplified to \frac{19}{2} by removing the negative sign from both the numerator and the denominator.
