|10a-8|=78
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.
10a-8=78 10a-8=-78
Whakamahia te tautuhinga o te uara pū.
10a=86 10a=-70
Me tāpiri 8 ki ngā taha e rua o te whārite.
a=\frac{43}{5} a=-7
Whakawehea ngā taha e rua ki te 10.
