-0.25x=-3-2.5
Tangohia te 2.5 mai i ngā taha e rua.
-0.25x=-5.5
Tangohia te 2.5 i te -3, ka -5.5.
x=\frac{-5.5}{-0.25}
Whakawehea ngā taha e rua ki te -0.25.
x=\frac{-550}{-25}
Whakarohaina te \frac{-5.5}{-0.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=22
Whakawehea te -550 ki te -25, kia riro ko 22.
