Kua tāruatia ki te papatopenga
2x+3x=\frac{30}{4}
Whakawehea ngā taha e rua ki te 4.
2x+3x=\frac{15}{2}
Whakahekea te hautanga \frac{30}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
5x=\frac{15}{2}
Pahekotia te 2x me 3x, ka 5x.
x=\frac{\frac{15}{2}}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{15}{2\times 5}
Tuhia te \frac{\frac{15}{2}}{5} hei hautanga kotahi.
x=\frac{15}{10}
Whakareatia te 2 ki te 5, ka 10.
x=\frac{3}{2}
Whakahekea te hautanga \frac{15}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
