Kua tāruatia ki te papatopenga
3-3y=1
Pahekotia te -2y me -y, ka -3y.
-3y=1-3
Tangohia te 3 mai i ngā taha e rua.
-3y=-2
Tangohia te 3 i te 1, ka -2.
y=\frac{-2}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{2}{3}
Ka taea te hautanga \frac{-2}{-3} te whakamāmā ki te \frac{2}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
