Kua tāruatia ki te papatopenga
4-5y=-5
Pahekotia te -2y me -3y, ka -5y.
-5y=-5-4
Tangohia te 4 mai i ngā taha e rua.
-5y=-9
Tangohia te 4 i te -5, ka -9.
y=\frac{-9}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{9}{5}
Ka taea te hautanga \frac{-9}{-5} te whakamāmā ki te \frac{9}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
