Kua tāruatia ki te papatopenga
-2+2x=5\times 2\times 50x
Tangohia te 4 i te 2, ka -2.
-2+2x=10\times 50x
Whakareatia te 5 ki te 2, ka 10.
-2+2x=500x
Whakareatia te 10 ki te 50, ka 500.
-2+2x-500x=0
Tangohia te 500x mai i ngā taha e rua.
-2-498x=0
Pahekotia te 2x me -500x, ka -498x.
-498x=2
Me tāpiri te 2 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{2}{-498}
Whakawehea ngā taha e rua ki te -498.
x=-\frac{1}{249}
Whakahekea te hautanga \frac{2}{-498} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
