Whakaoti i te 8/6=2y+4/75

$$\frac{ 8 }{ 6 } = \frac{ 2y+4 }{ 75 }$$

Whakaoti mō y

$$y=48$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 150, arā, te tauraro pātahi he tino iti rawa te kitea o 6,75.

$$25\times 8=2\left(2y+4\right)$$

Whakareatia te 25 ki te 8, ka 200.

$$200=2\left(2y+4\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2y+4.

$$200=4y+8$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$4y+8=200$$

Tangohia te 8 mai i ngā taha e rua.

$$4y=200-8$$

Tangohia te 8 i te 200, ka 192.

$$4y=192$$

Whakawehea ngā taha e rua ki te 4.

$$y=\frac{192}{4}$$

Whakawehea te 192 ki te 4, kia riro ko 48.

$$y=48$$
