Graph
Tohaina
Kua tāruatia ki te papatopenga
12x=90+0\times 5x
Whakareatia ngā taha e rua o te whārite ki te 2.
12x=90+0x
Whakareatia te 0 ki te 5, ka 0.
12x=90+0
Ko te tau i whakarea ki te kore ka hua ko te kore.
12x=90
Tāpirihia te 90 ki te 0, ka 90.
x=\frac{90}{12}
Whakawehea ngā taha e rua ki te 12.
x=\frac{15}{2}
Whakahekea te hautanga \frac{90}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
