Kua tāruatia ki te papatopenga
\frac{2x}{42+512}=3
Tātaihia te 2 mā te pū o 9, kia riro ko 512.
\frac{2x}{554}=3
Tāpirihia te 42 ki te 512, ka 554.
\frac{1}{277}x=3
Whakawehea te 2x ki te 554, kia riro ko \frac{1}{277}x.
x=3\times 277
Me whakarea ngā taha e rua ki te 277, te tau utu o \frac{1}{277}.
x=831
Whakareatia te 3 ki te 277, ka 831.
