2x-6=1.2-x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
2x-6+x=1.2
Me tāpiri te x ki ngā taha e rua.
3x-6=1.2
Pahekotia te 2x me x, ka 3x.
3x=1.2+6
Me tāpiri te 6 ki ngā taha e rua.
3x=7.2
Tāpirihia te 1.2 ki te 6, ka 7.2.
x=\frac{7.2}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{72}{30}
Whakarohaina te \frac{7.2}{3} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{12}{5}
Whakahekea te hautanga \frac{72}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
