Whakaoti i te 5/8y-3=1/2

$$\frac { 5 } { 8 } y - 3 = \frac { 1 } { 2 }$$

Whakaoti mō y

$$y = \frac{28}{5} = 5\frac{3}{5} = 5.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te 3 ki ngā taha e rua.

$$\frac{5}{8}y=\frac{1}{2}+3$$

Me tahuri te 3 ki te hautau \frac{6}{2}.

$$\frac{5}{8}y=\frac{1}{2}+\frac{6}{2}$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{6}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{5}{8}y=\frac{1+6}{2}$$

Tāpirihia te 1 ki te 6, ka 7.

$$\frac{5}{8}y=\frac{7}{2}$$

Me whakarea ngā taha e rua ki te \frac{8}{5}, te tau utu o \frac{5}{8}.

$$y=\frac{7}{2}\times \frac{8}{5}$$

Me whakarea te \frac{7}{2} ki te \frac{8}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$y=\frac{7\times 8}{2\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 8}{2\times 5}.

$$y=\frac{56}{10}$$

Whakahekea te hautanga \frac{56}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$y=\frac{28}{5}$$
