Kua tāruatia ki te papatopenga
18-x=\frac{27}{12}
Whakawehea ngā taha e rua ki te 12.
18-x=\frac{9}{4}
Whakahekea te hautanga \frac{27}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
-x=\frac{9}{4}-18
Tangohia te 18 mai i ngā taha e rua.
-x=\frac{9}{4}-\frac{72}{4}
Me tahuri te 18 ki te hautau \frac{72}{4}.
-x=\frac{9-72}{4}
Tā te mea he rite te tauraro o \frac{9}{4} me \frac{72}{4}, me tango rāua mā te tango i ō raua taurunga.
-x=-\frac{63}{4}
Tangohia te 72 i te 9, ka -63.
x=\frac{63}{4}
Me whakarea ngā taha e rua ki te -1.
