Kua tāruatia ki te papatopenga
y+4+3y=3
Whakareatia ngā taha e rua o te whārite ki te 3.
4y+4=3
Pahekotia te y me 3y, ka 4y.
4y=3-4
Tangohia te 4 mai i ngā taha e rua.
4y=-1
Tangohia te 4 i te 3, ka -1.
y=\frac{-1}{4}
Whakawehea ngā taha e rua ki te 4.
y=-\frac{1}{4}
Ka taea te hautanga \frac{-1}{4} te tuhi anō ko -\frac{1}{4} mā te tango i te tohu tōraro.
