0\left(38-4x\right)+19=4\left(8-0\times 5\right)+x
Whakareatia te 0 ki te 5, ka 0.
0+19=4\left(8-0\times 5\right)+x
Ko te tau i whakarea ki te kore ka hua ko te kore.
19=4\left(8-0\times 5\right)+x
Tāpirihia te 0 ki te 19, ka 19.
19=4\left(8-0\right)+x
Whakareatia te 0 ki te 5, ka 0.
19=4\times 8+x
Tangohia te 0 i te 8, ka 8.
19=32+x
Whakareatia te 4 ki te 8, ka 32.
32+x=19
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=19-32
Tangohia te 32 mai i ngā taha e rua.
x=-13
Tangohia te 32 i te 19, ka -13.
