Kua tāruatia ki te papatopenga
0.3x-0.5+0.4x=1
Me tāpiri te 0.4x ki ngā taha e rua.
0.7x-0.5=1
Pahekotia te 0.3x me 0.4x, ka 0.7x.
0.7x=1+0.5
Me tāpiri te 0.5 ki ngā taha e rua.
0.7x=1.5
Tāpirihia te 1 ki te 0.5, ka 1.5.
x=\frac{1.5}{0.7}
Whakawehea ngā taha e rua ki te 0.7.
x=\frac{15}{7}
Whakarohaina te \frac{1.5}{0.7} mā te whakarea i te taurunga me te tauraro ki te 10.
