6-3x-2\left(x-2\right)=5-3\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2-x.
6-3x-2x+4=5-3\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-2.
6-5x+4=5-3\left(x-3\right)
Pahekotia te -3x me -2x, ka -5x.
10-5x=5-3\left(x-3\right)
Tāpirihia te 6 ki te 4, ka 10.
10-5x=5-3x+9
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-3.
10-5x=14-3x
Tāpirihia te 5 ki te 9, ka 14.
10-5x+3x=14
Me tāpiri te 3x ki ngā taha e rua.
10-2x=14
Pahekotia te -5x me 3x, ka -2x.
-2x=14-10
Tangohia te 10 mai i ngā taha e rua.
-2x=4
Tangohia te 10 i te 14, ka 4.
x=\frac{4}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-2
Whakawehea te 4 ki te -2, kia riro ko -2.
