425x+850=10625x
Whakamahia te āhuatanga tohatoha hei whakarea te 425 ki te x+2.
425x+850-10625x=0
Tangohia te 10625x mai i ngā taha e rua.
-10200x+850=0
Pahekotia te 425x me -10625x, ka -10200x.
-10200x=-850
Tangohia te 850 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-850}{-10200}
Whakawehea ngā taha e rua ki te -10200.
x=\frac{1}{12}
Whakahekea te hautanga \frac{-850}{-10200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -850.
