2.6x-6.6=0.4x
Pahekotia te 2x me 0.6x, ka 2.6x.
2.6x-6.6-0.4x=0
Tangohia te 0.4x mai i ngā taha e rua.
2.2x-6.6=0
Pahekotia te 2.6x me -0.4x, ka 2.2x.
2.2x=6.6
Me tāpiri te 6.6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{6.6}{2.2}
Whakawehea ngā taha e rua ki te 2.2.
x=\frac{66}{22}
Whakarohaina te \frac{6.6}{2.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=3
Whakawehea te 66 ki te 22, kia riro ko 3.
