9x-6x+6=5\left(x+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te x-1.
3x+6=5\left(x+2\right)
Pahekotia te 9x me -6x, ka 3x.
3x+6=5x+10
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+2.
3x+6-5x=10
Tangohia te 5x mai i ngā taha e rua.
-2x+6=10
Pahekotia te 3x me -5x, ka -2x.
-2x=10-6
Tangohia te 6 mai i ngā taha e rua.
-2x=4
Tangohia te 6 i te 10, 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.
