Kua tāruatia ki te papatopenga
45x=60\left(2-x\right)
Whakareatia te 2 ki te 1, ka 2.
45x=120-60x
Whakamahia te āhuatanga tohatoha hei whakarea te 60 ki te 2-x.
45x+60x=120
Me tāpiri te 60x ki ngā taha e rua.
105x=120
Pahekotia te 45x me 60x, ka 105x.
x=\frac{120}{105}
Whakawehea ngā taha e rua ki te 105.
x=\frac{8}{7}
Whakahekea te hautanga \frac{120}{105} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.
