|7x-8|=5
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.
7x-8=5 7x-8=-5
Whakamahia te tautuhinga o te uara pū.
7x=13 7x=3
Me tāpiri 8 ki ngā taha e rua o te whārite.
x=\frac{13}{7} x=\frac{3}{7}
Whakawehea ngā taha e rua ki te 7.
