Kua tāruatia ki te papatopenga
5x-1=\frac{7}{4}\times 8
Me whakarea ngā taha e rua ki te 8.
5x-1=\frac{7\times 8}{4}
Tuhia te \frac{7}{4}\times 8 hei hautanga kotahi.
5x-1=\frac{56}{4}
Whakareatia te 7 ki te 8, ka 56.
5x-1=14
Whakawehea te 56 ki te 4, kia riro ko 14.
5x=14+1
Me tāpiri te 1 ki ngā taha e rua.
5x=15
Tāpirihia te 14 ki te 1, ka 15.
x=\frac{15}{5}
Whakawehea ngā taha e rua ki te 5.
x=3
Whakawehea te 15 ki te 5, kia riro ko 3.
