Kua tāruatia ki te papatopenga
8I+40I-2240=0
Whakamahia te āhuatanga tohatoha hei whakarea te 40 ki te I-56.
48I-2240=0
Pahekotia te 8I me 40I, ka 48I.
48I=2240
Me tāpiri te 2240 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
I=\frac{2240}{48}
Whakawehea ngā taha e rua ki te 48.
I=\frac{140}{3}
Whakahekea te hautanga \frac{2240}{48} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.
