Kua tāruatia ki te papatopenga
-3y+2-14y=-40
Whakareatia ngā taha e rua o te whārite ki te 2.
-17y+2=-40
Pahekotia te -3y me -14y, ka -17y.
-17y=-40-2
Tangohia te 2 mai i ngā taha e rua.
-17y=-42
Tangohia te 2 i te -40, ka -42.
y=\frac{-42}{-17}
Whakawehea ngā taha e rua ki te -17.
y=\frac{42}{17}
Ka taea te hautanga \frac{-42}{-17} te whakamāmā ki te \frac{42}{17} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
