2x-4-3=9\left(1-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-2.
2x-7=9\left(1-x\right)
Tangohia te 3 i te -4, ka -7.
2x-7=9-9x
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 1-x.
2x-7+9x=9
Me tāpiri te 9x ki ngā taha e rua.
11x-7=9
Pahekotia te 2x me 9x, ka 11x.
11x=9+7
Me tāpiri te 7 ki ngā taha e rua.
11x=16
Tāpirihia te 9 ki te 7, ka 16.
x=\frac{16}{11}
Whakawehea ngā taha e rua ki te 11.
