Whakaoti i te y_{0}=-2*25/16-25/4+6

$$y _ { 0 } = - 2 \cdot \frac { 25 } { 16 } - \frac { 25 } { 4 } + 6$$

Whakaoti mō y_0

$$y_{0} = -\frac{27}{8} = -3\frac{3}{8} = -3.375$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te -2\times \frac{25}{16} hei hautanga kotahi.

$$y_{0}=\frac{-2\times 25}{16}-\frac{25}{4}+6$$

Whakareatia te -2 ki te 25, ka -50.

$$y_{0}=\frac{-50}{16}-\frac{25}{4}+6$$

Whakahekea te hautanga \frac{-50}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$y_{0}=-\frac{25}{8}-\frac{25}{4}+6$$

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri -\frac{25}{8} me \frac{25}{4} ki te hautau me te tautūnga 8.

$$y_{0}=-\frac{25}{8}-\frac{50}{8}+6$$

Tā te mea he rite te tauraro o -\frac{25}{8} me \frac{50}{8}, me tango rāua mā te tango i ō raua taurunga.

$$y_{0}=\frac{-25-50}{8}+6$$

Tangohia te 50 i te -25, ka -75.

$$y_{0}=-\frac{75}{8}+6$$

Me tahuri te 6 ki te hautau \frac{48}{8}.

$$y_{0}=-\frac{75}{8}+\frac{48}{8}$$

Tā te mea he rite te tauraro o -\frac{75}{8} me \frac{48}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$y_{0}=\frac{-75+48}{8}$$

Tāpirihia te -75 ki te 48, ka -27.

$$y_{0}=-\frac{27}{8}$$

Tautapa y_0

$$y_{0}≔-\frac{27}{8}$$
