Kua tāruatia ki te papatopenga
6x-14+2x=12
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x-7.
8x-14=12
Pahekotia te 6x me 2x, ka 8x.
8x=12+14
Me tāpiri te 14 ki ngā taha e rua.
8x=26
Tāpirihia te 12 ki te 14, ka 26.
x=\frac{26}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{13}{4}
Whakahekea te hautanga \frac{26}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
