12x+8=48-8x
Pahekotia te 19x me -7x, ka 12x.
12x+8+8x=48
Me tāpiri te 8x ki ngā taha e rua.
20x+8=48
Pahekotia te 12x me 8x, ka 20x.
20x=48-8
Tangohia te 8 mai i ngā taha e rua.
20x=40
Tangohia te 8 i te 48, ka 40.
x=\frac{40}{20}
Whakawehea ngā taha e rua ki te 20.
x=2
Whakawehea te 40 ki te 20, kia riro ko 2.
