5.6x+6=80.8-1.2x
Pahekotia te 8.4x me -2.8x, ka 5.6x.
5.6x+6+1.2x=80.8
Me tāpiri te 1.2x ki ngā taha e rua.
6.8x+6=80.8
Pahekotia te 5.6x me 1.2x, ka 6.8x.
6.8x=80.8-6
Tangohia te 6 mai i ngā taha e rua.
6.8x=74.8
Tangohia te 6 i te 80.8, ka 74.8.
x=\frac{74.8}{6.8}
Whakawehea ngā taha e rua ki te 6.8.
x=\frac{748}{68}
Whakarohaina te \frac{74.8}{6.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x=11
Whakawehea te 748 ki te 68, kia riro ko 11.
