Whakaoti i te 5-n-2/25=-15/25

$$5 - n - \frac { 2 } { 25 } = - \frac { 15 } { 25 }$$

Whakaoti mō n

$$n = \frac{138}{25} = 5\frac{13}{25} = 5.52$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tahuri te 5 ki te hautau \frac{125}{25}.

$$\frac{125}{25}-n-\frac{2}{25}=-\frac{15}{25}$$

Tā te mea he rite te tauraro o \frac{125}{25} me \frac{2}{25}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{125-2}{25}-n=-\frac{15}{25}$$

Tangohia te 2 i te 125, ka 123.

$$\frac{123}{25}-n=-\frac{15}{25}$$

Whakahekea te hautanga \frac{15}{25} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{123}{25}-n=-\frac{3}{5}$$

Tangohia te \frac{123}{25} mai i ngā taha e rua.

$$-n=-\frac{3}{5}-\frac{123}{25}$$

Ko te maha noa iti rawa atu o 5 me 25 ko 25. Me tahuri -\frac{3}{5} me \frac{123}{25} ki te hautau me te tautūnga 25.

$$-n=-\frac{15}{25}-\frac{123}{25}$$

Tā te mea he rite te tauraro o -\frac{15}{25} me \frac{123}{25}, me tango rāua mā te tango i ō raua taurunga.

$$-n=\frac{-15-123}{25}$$

Tangohia te 123 i te -15, ka -138.

$$-n=-\frac{138}{25}$$

Me whakarea ngā taha e rua ki te -1.

$$n=\frac{138}{25}$$
