-x=\frac{7}{2}-\frac{3}{2}
Tangohia te \frac{3}{2} mai i ngā taha e rua.
-x=\frac{7-3}{2}
Tā te mea he rite te tauraro o \frac{7}{2} me \frac{3}{2}, me tango rāua mā te tango i ō raua taurunga.
-x=\frac{4}{2}
Tangohia te 3 i te 7, ka 4.
-x=2
Whakawehea te 4 ki te 2, kia riro ko 2.
x=-2
Me whakarea ngā taha e rua ki te -1.
