Kua tāruatia ki te papatopenga
8+44+x+x+0\times 4=20
Whakareatia ngā taha e rua o te whārite ki te 4.
52+x+x+0\times 4=20
Tāpirihia te 8 ki te 44, ka 52.
52+2x+0\times 4=20
Pahekotia te x me x, ka 2x.
52+2x+0=20
Whakareatia te 0 ki te 4, ka 0.
52+2x=20
Tāpirihia te 52 ki te 0, ka 52.
2x=20-52
Tangohia te 52 mai i ngā taha e rua.
2x=-32
Tangohia te 52 i te 20, ka -32.
x=\frac{-32}{2}
Whakawehea ngā taha e rua ki te 2.
x=-16
Whakawehea te -32 ki te 2, kia riro ko -16.
