0.4x+1.6+0.3x=2.5
Me tāpiri te 0.3x ki ngā taha e rua.
0.7x+1.6=2.5
Pahekotia te 0.4x me 0.3x, ka 0.7x.
0.7x=2.5-1.6
Tangohia te 1.6 mai i ngā taha e rua.
0.7x=0.9
Tangohia te 1.6 i te 2.5, ka 0.9.
x=\frac{0.9}{0.7}
Whakawehea ngā taha e rua ki te 0.7.
x=\frac{9}{7}
Whakarohaina te \frac{0.9}{0.7} mā te whakarea i te taurunga me te tauraro ki te 10.
