x+22-21x=0
Tangohia te 21x mai i ngā taha e rua.
-20x+22=0
Pahekotia te x me -21x, ka -20x.
-20x=-22
Tangohia te 22 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-22}{-20}
Whakawehea ngā taha e rua ki te -20.
x=\frac{11}{10}
Whakahekea te hautanga \frac{-22}{-20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
