Kua tāruatia ki te papatopenga
12x+5-2x=28-4x
Whakareatia ngā taha e rua o te whārite ki te 4.
10x+5=28-4x
Pahekotia te 12x me -2x, ka 10x.
10x+5+4x=28
Me tāpiri te 4x ki ngā taha e rua.
14x+5=28
Pahekotia te 10x me 4x, ka 14x.
14x=28-5
Tangohia te 5 mai i ngā taha e rua.
14x=23
Tangohia te 5 i te 28, ka 23.
x=\frac{23}{14}
Whakawehea ngā taha e rua ki te 14.
