3x+12=35-4x-9
Pahekotia te 5x me -2x, ka 3x.
3x+12=26-4x
Tangohia te 9 i te 35, ka 26.
3x+12+4x=26
Me tāpiri te 4x ki ngā taha e rua.
7x+12=26
Pahekotia te 3x me 4x, ka 7x.
7x=26-12
Tangohia te 12 mai i ngā taha e rua.
7x=14
Tangohia te 12 i te 26, ka 14.
x=\frac{14}{7}
Whakawehea ngā taha e rua ki te 7.
x=2
Whakawehea te 14 ki te 7, kia riro ko 2.
