4x-3-6x-12=3\left(2x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 3x+6.
-2x-3-12=3\left(2x-1\right)
Pahekotia te 4x me -6x, ka -2x.
-2x-15=3\left(2x-1\right)
Tangohia te 12 i te -3, ka -15.
-2x-15=6x-3
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-1.
-2x-15-6x=-3
Tangohia te 6x mai i ngā taha e rua.
-8x-15=-3
Pahekotia te -2x me -6x, ka -8x.
-8x=-3+15
Me tāpiri te 15 ki ngā taha e rua.
-8x=12
Tāpirihia te -3 ki te 15, ka 12.
x=\frac{12}{-8}
Whakawehea ngā taha e rua ki te -8.
x=-\frac{3}{2}
Whakahekea te hautanga \frac{12}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
