Graph
Tohaina
Kua tāruatia ki te papatopenga
y=\frac{8}{-2}
Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te -2.
y=-4
Whakawehea te 8 ki te -2, kia riro ko -4.
x+4\left(-4\right)=-4
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
x-16=-4
Whakareatia te 4 ki te -4, ka -16.
x=-4+16
Me tāpiri te 16 ki ngā taha e rua.
x=12
Tāpirihia te -4 ki te 16, ka 12.
x=12 y=-4
Kua oti te pūnaha te whakatau.
