2x-4-3=-2\left(2x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-2.
2x-7=-2\left(2x-1\right)
Tangohia te 3 i te -4, ka -7.
2x-7=-4x+2
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 2x-1.
2x-7+4x=2
Me tāpiri te 4x ki ngā taha e rua.
6x-7=2
Pahekotia te 2x me 4x, ka 6x.
6x=2+7
Me tāpiri te 7 ki ngā taha e rua.
6x=9
Tāpirihia te 2 ki te 7, ka 9.
x=\frac{9}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{3}{2}
Whakahekea te hautanga \frac{9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
