160=19+\frac{3}{4}x-17
Whakareatia te 5 ki te 32, ka 160.
160=2+\frac{3}{4}x
Tangohia te 17 i te 19, ka 2.
2+\frac{3}{4}x=160
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{3}{4}x=160-2
Tangohia te 2 mai i ngā taha e rua.
\frac{3}{4}x=158
Tangohia te 2 i te 160, ka 158.
x=158\times \frac{4}{3}
Me whakarea ngā taha e rua ki te \frac{4}{3}, te tau utu o \frac{3}{4}.
x=\frac{158\times 4}{3}
Tuhia te 158\times \frac{4}{3} hei hautanga kotahi.
x=\frac{632}{3}
Whakareatia te 158 ki te 4, ka 632.
