Kua tāruatia ki te papatopenga
x+85=\frac{123}{6}
Whakawehea ngā taha e rua ki te 6.
x+85=\frac{41}{2}
Whakahekea te hautanga \frac{123}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
x=\frac{41}{2}-85
Tangohia te 85 mai i ngā taha e rua.
x=\frac{41}{2}-\frac{170}{2}
Me tahuri te 85 ki te hautau \frac{170}{2}.
x=\frac{41-170}{2}
Tā te mea he rite te tauraro o \frac{41}{2} me \frac{170}{2}, me tango rāua mā te tango i ō raua taurunga.
x=-\frac{129}{2}
Tangohia te 170 i te 41, ka -129.
