Whakaoti i te -1/5y+1/3=-1/4

$$- \frac { 1 } { 5 } y + \frac { 1 } { 3 } = - \frac { 1 } { 4 }$$

Whakaoti mō y

$$y = \frac{35}{12} = 2\frac{11}{12} \approx 2.916666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{3} mai i ngā taha e rua.

$$-\frac{1}{5}y=-\frac{1}{4}-\frac{1}{3}$$

Ko te maha noa iti rawa atu o 4 me 3 ko 12. Me tahuri -\frac{1}{4} me \frac{1}{3} ki te hautau me te tautūnga 12.

$$-\frac{1}{5}y=-\frac{3}{12}-\frac{4}{12}$$

Tā te mea he rite te tauraro o -\frac{3}{12} me \frac{4}{12}, me tango rāua mā te tango i ō raua taurunga.

$$-\frac{1}{5}y=\frac{-3-4}{12}$$

Tangohia te 4 i te -3, ka -7.

$$-\frac{1}{5}y=-\frac{7}{12}$$

Me whakarea ngā taha e rua ki te -5, te tau utu o -\frac{1}{5}.

$$y=-\frac{7}{12}\left(-5\right)$$

Tuhia te -\frac{7}{12}\left(-5\right) hei hautanga kotahi.

$$y=\frac{-7\left(-5\right)}{12}$$

Whakareatia te -7 ki te -5, ka 35.

$$y=\frac{35}{12}$$
