|9x|-2=61
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.
|9x|=63
Me tāpiri 2 ki ngā taha e rua o te whārite.
9x=63 9x=-63
Whakamahia te tautuhinga o te uara pū.
x=7 x=-7
Whakawehea ngā taha e rua ki te 9.
