-1.4k+9.8+7=5.6
Whakamahia te āhuatanga tohatoha hei whakarea te -1.4 ki te k-7.
-1.4k+16.8=5.6
Tāpirihia te 9.8 ki te 7, ka 16.8.
-1.4k=5.6-16.8
Tangohia te 16.8 mai i ngā taha e rua.
-1.4k=-11.2
Tangohia te 16.8 i te 5.6, ka -11.2.
k=\frac{-11.2}{-1.4}
Whakawehea ngā taha e rua ki te -1.4.
k=\frac{-112}{-14}
Whakarohaina te \frac{-11.2}{-1.4} mā te whakarea i te taurunga me te tauraro ki te 10.
k=8
Whakawehea te -112 ki te -14, kia riro ko 8.
