Kua tāruatia ki te papatopenga
400y=40\times 5^{2}+26y
Whakareatia ngā taha e rua o te whārite ki te 40.
400y=40\times 25+26y
Tātaihia te 5 mā te pū o 2, kia riro ko 25.
400y=1000+26y
Whakareatia te 40 ki te 25, ka 1000.
400y-26y=1000
Tangohia te 26y mai i ngā taha e rua.
374y=1000
Pahekotia te 400y me -26y, ka 374y.
y=\frac{1000}{374}
Whakawehea ngā taha e rua ki te 374.
y=\frac{500}{187}
Whakahekea te hautanga \frac{1000}{374} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
