20-3y=18
Multiply 4 and 5 to get 20.
-3y=18-20
Subtract 20 from both sides.
-3y=-2
Subtract 20 from 18 to get -2.
y=\frac{-2}{-3}
Divide both sides by -3.
y=\frac{2}{3}
Fraction \frac{-2}{-3} can be simplified to \frac{2}{3} by removing the negative sign from both the numerator and the denominator.
