Kua tāruatia ki te papatopenga
4x-3-2x=-\frac{2}{3}
Tangohia te 2x mai i ngā taha e rua.
2x-3=-\frac{2}{3}
Pahekotia te 4x me -2x, ka 2x.
2x=-\frac{2}{3}+3
Me tāpiri te 3 ki ngā taha e rua.
2x=-\frac{2}{3}+\frac{9}{3}
Me tahuri te 3 ki te hautau \frac{9}{3}.
2x=\frac{-2+9}{3}
Tā te mea he rite te tauraro o -\frac{2}{3} me \frac{9}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
2x=\frac{7}{3}
Tāpirihia te -2 ki te 9, ka 7.
x=\frac{\frac{7}{3}}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{7}{3\times 2}
Tuhia te \frac{\frac{7}{3}}{2} hei hautanga kotahi.
x=\frac{7}{6}
Whakareatia te 3 ki te 2, ka 6.
