|7x+5|=4
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+5=4 7x+5=-4
Whakamahia te tautuhinga o te uara pū.
7x=-1 7x=-9
Me tango 5 mai i ngā taha e rua o te whārite.
x=-\frac{1}{7} x=-\frac{9}{7}
Whakawehea ngā taha e rua ki te 7.
