Kua tāruatia ki te papatopenga
x+7=\frac{1}{4}\times 8
Me whakarea ngā taha e rua ki te 8, te tau utu o \frac{1}{8}.
x+7=\frac{8}{4}
Whakareatia te \frac{1}{4} ki te 8, ka \frac{8}{4}.
x+7=2
Whakawehea te 8 ki te 4, kia riro ko 2.
x=2-7
Tangohia te 7 mai i ngā taha e rua.
x=-5
Tangohia te 7 i te 2, ka -5.
