3x^{2}+2x-1+2x=1+3x^{2}
Me tāpiri te 2x ki ngā taha e rua.
3x^{2}+4x-1=1+3x^{2}
Pahekotia te 2x me 2x, ka 4x.
3x^{2}+4x-1-3x^{2}=1
Tangohia te 3x^{2} mai i ngā taha e rua.
4x-1=1
Pahekotia te 3x^{2} me -3x^{2}, ka 0.
4x=1+1
Me tāpiri te 1 ki ngā taha e rua.
4x=2
Tāpirihia te 1 ki te 1, ka 2.
x=\frac{2}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{1}{2}
Whakahekea te hautanga \frac{2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
