Kua tāruatia ki te papatopenga
x=\frac{1}{2}-4
Tangohia te 4 mai i ngā taha e rua.
x=\frac{1}{2}-\frac{8}{2}
Me tahuri te 4 ki te hautau \frac{8}{2}.
x=\frac{1-8}{2}
Tā te mea he rite te tauraro o \frac{1}{2} me \frac{8}{2}, me tango rāua mā te tango i ō raua taurunga.
x=-\frac{7}{2}
Tangohia te 8 i te 1, ka -7.
