Graph
Tohaina
Kua tāruatia ki te papatopenga
x=6+2
Whakaarohia te whārite tuarua. Me tāpiri te 2 ki ngā taha e rua.
x=8
Tāpirihia te 6 ki te 2, ka 8.
3\times 8-y=3
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
24-y=3
Whakareatia te 3 ki te 8, ka 24.
-y=3-24
Tangohia te 24 mai i ngā taha e rua.
-y=-21
Tangohia te 24 i te 3, ka -21.
y=\frac{-21}{-1}
Whakawehea ngā taha e rua ki te -1.
y=21
Ka taea te hautanga \frac{-21}{-1} te whakamāmā ki te 21 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
x=8 y=21
Kua oti te pūnaha te whakatau.
