Kua tāruatia ki te papatopenga
0.7x=0.5+3.7
Me tāpiri te 3.7 ki ngā taha e rua.
0.7x=4.2
Tāpirihia te 0.5 ki te 3.7, ka 4.2.
x=\frac{4.2}{0.7}
Whakawehea ngā taha e rua ki te 0.7.
x=\frac{42}{7}
Whakarohaina te \frac{4.2}{0.7} mā te whakarea i te taurunga me te tauraro ki te 10.
x=6
Whakawehea te 42 ki te 7, kia riro ko 6.
