2|5x+8|-1=11
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.
2|5x+8|=12
Me tāpiri 1 ki ngā taha e rua o te whārite.
|5x+8|=6
Whakawehea ngā taha e rua ki te 2.
5x+8=6 5x+8=-6
Whakamahia te tautuhinga o te uara pū.
5x=-2 5x=-14
Me tango 8 mai i ngā taha e rua o te whārite.
x=-\frac{2}{5} x=-\frac{14}{5}
Whakawehea ngā taha e rua ki te 5.
