|18x-2.5|=12
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.
18x-2.5=12 18x-2.5=-12
Whakamahia te tautuhinga o te uara pū.
18x=14.5 18x=-9.5
Me tāpiri 2.5 ki ngā taha e rua o te whārite.
x=\frac{29}{36} x=-\frac{19}{36}
Whakawehea ngā taha e rua ki te 18.
