32=2+\frac{3}{4}x
Tangohia te 17 i te 19, ka 2.
2+\frac{3}{4}x=32
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{3}{4}x=32-2
Tangohia te 2 mai i ngā taha e rua.
\frac{3}{4}x=30
Tangohia te 2 i te 32, ka 30.
x=30\times \frac{4}{3}
Me whakarea ngā taha e rua ki te \frac{4}{3}, te tau utu o \frac{3}{4}.
x=\frac{30\times 4}{3}
Tuhia te 30\times \frac{4}{3} hei hautanga kotahi.
x=\frac{120}{3}
Whakareatia te 30 ki te 4, ka 120.
x=40
Whakawehea te 120 ki te 3, kia riro ko 40.
