Whakaoti i te -27/4=y+2/2-3(y+2)/4

$$- \frac { 27 } { 4 } = \frac { y + 2 } { 2 } - \frac { 3 ( y + 2 ) } { 4 }$$

Whakaoti mō y

$$y=25$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 4,2.

$$-27=2\left(y+2\right)-3\left(y+2\right)$$

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

$$-27=2y+4-3\left(y+2\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te y+2.

$$-27=2y+4-3y-6$$

Pahekotia te 2y me -3y, ka -y.

$$-27=-y+4-6$$

Tangohia te 6 i te 4, ka -2.

$$-27=-y-2$$

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

$$-y-2=-27$$

Me tāpiri te 2 ki ngā taha e rua.

$$-y=-27+2$$

Tāpirihia te -27 ki te 2, ka -25.

$$-y=-25$$

Me whakarea ngā taha e rua ki te -1.

$$y=25$$
