Kua tāruatia ki te papatopenga
-3+4x=5\times 4+1
Whakareatia ngā taha e rua o te whārite ki te 4.
-3+4x=20+1
Whakareatia te 5 ki te 4, ka 20.
-3+4x=21
Tāpirihia te 20 ki te 1, ka 21.
4x=21+3
Me tāpiri te 3 ki ngā taha e rua.
4x=24
Tāpirihia te 21 ki te 3, ka 24.
x=\frac{24}{4}
Whakawehea ngā taha e rua ki te 4.
x=6
Whakawehea te 24 ki te 4, kia riro ko 6.
