Kua tāruatia ki te papatopenga
0.6x+36=87.6
Whakareatia te 0.4 ki te 90, ka 36.
0.6x=87.6-36
Tangohia te 36 mai i ngā taha e rua.
0.6x=51.6
Tangohia te 36 i te 87.6, ka 51.6.
x=\frac{51.6}{0.6}
Whakawehea ngā taha e rua ki te 0.6.
x=\frac{516}{6}
Whakarohaina te \frac{51.6}{0.6} mā te whakarea i te taurunga me te tauraro ki te 10.
x=86
Whakawehea te 516 ki te 6, kia riro ko 86.
