|-7x+3|=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+3=4 -7x+3=-4
Whakamahia te tautuhinga o te uara pū.
-7x=1 -7x=-7
Me tango 3 mai i ngā taha e rua o te whārite.
x=-\frac{1}{7} x=1
Whakawehea ngā taha e rua ki te -7.
