9x-9=6\left(x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x-1.
9x-9=6x+18
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x+3.
9x-9-6x=18
Tangohia te 6x mai i ngā taha e rua.
3x-9=18
Pahekotia te 9x me -6x, ka 3x.
3x=18+9
Me tāpiri te 9 ki ngā taha e rua.
3x=27
Tāpirihia te 18 ki te 9, ka 27.
x=\frac{27}{3}
Whakawehea ngā taha e rua ki te 3.
x=9
Whakawehea te 27 ki te 3, kia riro ko 9.
