Kua tāruatia ki te papatopenga
3\times 5+2y=7
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
15+2y=7
Whakareatia te 3 ki te 5, ka 15.
2y=7-15
Tangohia te 15 mai i ngā taha e rua.
2y=-8
Tangohia te 15 i te 7, ka -8.
y=\frac{-8}{2}
Whakawehea ngā taha e rua ki te 2.
y=-4
Whakawehea te -8 ki te 2, kia riro ko -4.
x=5 y=-4
Kua oti te pūnaha te whakatau.
