Kua tāruatia ki te papatopenga
\frac{3}{4}x=7+5
Me tāpiri te 5 ki ngā taha e rua.
\frac{3}{4}x=12
Tāpirihia te 7 ki te 5, ka 12.
x=12\times \frac{4}{3}
Me whakarea ngā taha e rua ki te \frac{4}{3}, te tau utu o \frac{3}{4}.
x=\frac{12\times 4}{3}
Tuhia te 12\times \frac{4}{3} hei hautanga kotahi.
x=\frac{48}{3}
Whakareatia te 12 ki te 4, ka 48.
x=16
Whakawehea te 48 ki te 3, kia riro ko 16.
