Kua tāruatia ki te papatopenga
40x=-50x+100
Whakamahia te āhuatanga tohatoha hei whakarea te -50 ki te x-2.
40x+50x=100
Me tāpiri te 50x ki ngā taha e rua.
90x=100
Pahekotia te 40x me 50x, ka 90x.
x=\frac{100}{90}
Whakawehea ngā taha e rua ki te 90.
x=\frac{10}{9}
Whakahekea te hautanga \frac{100}{90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
