12-3x+3=2\left(x-2\right)-\left(x+5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-1.
15-3x=2\left(x-2\right)-\left(x+5\right)
Tāpirihia te 12 ki te 3, ka 15.
15-3x=2x-4-\left(x+5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-2.
15-3x=2x-4-x-5
Hei kimi i te tauaro o x+5, kimihia te tauaro o ia taurangi.
15-3x=x-4-5
Pahekotia te 2x me -x, ka x.
15-3x=x-9
Tangohia te 5 i te -4, ka -9.
15-3x-x=-9
Tangohia te x mai i ngā taha e rua.
15-4x=-9
Pahekotia te -3x me -x, ka -4x.
-4x=-9-15
Tangohia te 15 mai i ngā taha e rua.
-4x=-24
Tangohia te 15 i te -9, ka -24.
x=\frac{-24}{-4}
Whakawehea ngā taha e rua ki te -4.
x=6
Whakawehea te -24 ki te -4, kia riro ko 6.
