Kua tāruatia ki te papatopenga
7x-36=130x
Whakareatia te 26 ki te 5, ka 130.
7x-36-130x=0
Tangohia te 130x mai i ngā taha e rua.
-123x-36=0
Pahekotia te 7x me -130x, ka -123x.
-123x=36
Me tāpiri te 36 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{36}{-123}
Whakawehea ngā taha e rua ki te -123.
x=-\frac{12}{41}
Whakahekea te hautanga \frac{36}{-123} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
