Tohaina
Kua tāruatia ki te papatopenga
a\times \frac{4}{7}=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
a=-2\times \frac{7}{4}
Me whakarea ngā taha e rua ki te \frac{7}{4}, te tau utu o \frac{4}{7}.
a=\frac{-2\times 7}{4}
Tuhia te -2\times \frac{7}{4} hei hautanga kotahi.
a=\frac{-14}{4}
Whakareatia te -2 ki te 7, ka -14.
a=-\frac{7}{2}
Whakahekea te hautanga \frac{-14}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
