Kua tāruatia ki te papatopenga
3x-7=15-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5-x.
3x-7+3x=15
Me tāpiri te 3x ki ngā taha e rua.
6x-7=15
Pahekotia te 3x me 3x, ka 6x.
6x=15+7
Me tāpiri te 7 ki ngā taha e rua.
6x=22
Tāpirihia te 15 ki te 7, ka 22.
x=\frac{22}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{11}{3}
Whakahekea te hautanga \frac{22}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
