Kua tāruatia ki te papatopenga
-1+6\left(7-2\right)R=29
Whakawehea te 4 ki te 2, kia riro ko 2.
-1+6\times 5R=29
Tangohia te 2 i te 7, ka 5.
-1+30R=29
Whakareatia te 6 ki te 5, ka 30.
30R=29+1
Me tāpiri te 1 ki ngā taha e rua.
30R=30
Tāpirihia te 29 ki te 1, ka 30.
R=\frac{30}{30}
Whakawehea ngā taha e rua ki te 30.
R=1
Whakawehea te 30 ki te 30, kia riro ko 1.
