Tohaina
Kua tāruatia ki te papatopenga
1.5x+1.2x=38-x
Whakareatia te 1.5 ki te 0.8, ka 1.2.
2.7x=38-x
Pahekotia te 1.5x me 1.2x, ka 2.7x.
2.7x+x=38
Me tāpiri te x ki ngā taha e rua.
3.7x=38
Pahekotia te 2.7x me x, ka 3.7x.
x=\frac{38}{3.7}
Whakawehea ngā taha e rua ki te 3.7.
x=\frac{380}{37}
Whakarohaina te \frac{38}{3.7} mā te whakarea i te taurunga me te tauraro ki te 10.
