Kua tāruatia ki te papatopenga
4x+12\times 5=8
Whakareatia te 3 ki te 4, ka 12.
4x+60=8
Whakareatia te 12 ki te 5, ka 60.
4x=8-60
Tangohia te 60 mai i ngā taha e rua.
4x=-52
Tangohia te 60 i te 8, ka -52.
x=\frac{-52}{4}
Whakawehea ngā taha e rua ki te 4.
x=-13
Whakawehea te -52 ki te 4, kia riro ko -13.
