1.5x-0.7+1.2x=1.1
Me tāpiri te 1.2x ki ngā taha e rua.
2.7x-0.7=1.1
Pahekotia te 1.5x me 1.2x, ka 2.7x.
2.7x=1.1+0.7
Me tāpiri te 0.7 ki ngā taha e rua.
2.7x=1.8
Tāpirihia te 1.1 ki te 0.7, ka 1.8.
x=\frac{1.8}{2.7}
Whakawehea ngā taha e rua ki te 2.7.
x=\frac{18}{27}
Whakarohaina te \frac{1.8}{2.7} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{2}{3}
Whakahekea te hautanga \frac{18}{27} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.
