10=-22x+40
Tāpirihia te -16 ki te 56, ka 40.
-22x+40=10
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-22x=10-40
Tangohia te 40 mai i ngā taha e rua.
-22x=-30
Tangohia te 40 i te 10, ka -30.
x=\frac{-30}{-22}
Whakawehea ngā taha e rua ki te -22.
x=\frac{15}{11}
Whakahekea te hautanga \frac{-30}{-22} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
