10|x-3|=40
Pahekotia ngā kīanga tau ōrite me te whakamahi i ngā āhuatanga o te ōritetanga kia kitea te taurangi ki tētahi taha o te tohu ōrite me ngā tau ki tērā atu taha. Me maumahara ki te whai i te raupapa o ngā paheko.
|x-3|=4
Whakawehea ngā taha e rua ki te 10.
x-3=4 x-3=-4
Whakamahia te tautuhinga o te uara pū.
x=7 x=-1
Me tāpiri 3 ki ngā taha e rua o te whārite.
