Graph
Tohaina
Kua tāruatia ki te papatopenga
\frac{2}{5}x=4+1
Me tāpiri te 1 ki ngā taha e rua.
\frac{2}{5}x=5
Tāpirihia te 4 ki te 1, ka 5.
x=5\times \frac{5}{2}
Me whakarea ngā taha e rua ki te \frac{5}{2}, te tau utu o \frac{2}{5}.
x=\frac{5\times 5}{2}
Tuhia te 5\times \frac{5}{2} hei hautanga kotahi.
x=\frac{25}{2}
Whakareatia te 5 ki te 5, ka 25.
