-27=-7w+5w-15
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te w-3.
-27=-2w-15
Pahekotia te -7w me 5w, ka -2w.
-2w-15=-27
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2w=-27+15
Me tāpiri te 15 ki ngā taha e rua.
-2w=-12
Tāpirihia te -27 ki te 15, ka -12.
w=\frac{-12}{-2}
Whakawehea ngā taha e rua ki te -2.
w=6
Whakawehea te -12 ki te -2, kia riro ko 6.
