|18x-25|=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-25=12 18x-25=-12
Whakamahia te tautuhinga o te uara pū.
18x=37 18x=13
Me tāpiri 25 ki ngā taha e rua o te whārite.
x=\frac{37}{18} x=\frac{13}{18}
Whakawehea ngā taha e rua ki te 18.
