Kua tāruatia ki te papatopenga
2x+24+12x=-4
Me tāpiri te 12x ki ngā taha e rua.
14x+24=-4
Pahekotia te 2x me 12x, ka 14x.
14x=-4-24
Tangohia te 24 mai i ngā taha e rua.
14x=-28
Tangohia te 24 i te -4, ka -28.
x=\frac{-28}{14}
Whakawehea ngā taha e rua ki te 14.
x=-2
Whakawehea te -28 ki te 14, kia riro ko -2.
