Tohaina
Kua tāruatia ki te papatopenga
3x+54+15x=-30
Me tāpiri te 15x ki ngā taha e rua.
18x+54=-30
Pahekotia te 3x me 15x, ka 18x.
18x=-30-54
Tangohia te 54 mai i ngā taha e rua.
18x=-84
Tangohia te 54 i te -30, ka -84.
x=\frac{-84}{18}
Whakawehea ngā taha e rua ki te 18.
x=-\frac{14}{3}
Whakahekea te hautanga \frac{-84}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
