Kua tāruatia ki te papatopenga
24-x=\frac{2}{5}x
Whakareatia te 2 ki te \frac{1}{5}, ka \frac{2}{5}.
24-x-\frac{2}{5}x=0
Tangohia te \frac{2}{5}x mai i ngā taha e rua.
24-\frac{7}{5}x=0
Pahekotia te -x me -\frac{2}{5}x, ka -\frac{7}{5}x.
-\frac{7}{5}x=-24
Tangohia te 24 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-24\left(-\frac{5}{7}\right)
Me whakarea ngā taha e rua ki te -\frac{5}{7}, te tau utu o -\frac{7}{5}.
x=\frac{-24\left(-5\right)}{7}
Tuhia te -24\left(-\frac{5}{7}\right) hei hautanga kotahi.
x=\frac{120}{7}
Whakareatia te -24 ki te -5, ka 120.
