Whakaoti i te 9(-4-3/2y)-2z=28

$$9(-4- \frac{ 3 }{ 2 } y)-2z=28$$

Whakaoti mō y

$$y=\frac{-4z-128}{27}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te -4-\frac{3}{2}y.

$$-36-\frac{27}{2}y-2z=28$$

Me tāpiri te 36 ki ngā taha e rua.

$$-\frac{27}{2}y-2z=28+36$$

Tāpirihia te 28 ki te 36, ka 64.

$$-\frac{27}{2}y-2z=64$$

Me tāpiri te 2z ki ngā taha e rua.

$$-\frac{27}{2}y=64+2z$$

He hanga arowhānui tō te whārite.

$$-\frac{27}{2}y=2z+64$$

Whakawehea ngā taha e rua o te whārite ki te -\frac{27}{2}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{-\frac{27}{2}y}{-\frac{27}{2}}=\frac{2z+64}{-\frac{27}{2}}$$

Mā te whakawehe ki te -\frac{27}{2} ka wetekia te whakareanga ki te -\frac{27}{2}.

$$y=\frac{2z+64}{-\frac{27}{2}}$$

Whakawehe 64+2z ki te -\frac{27}{2} mā te whakarea 64+2z ki te tau huripoki o -\frac{27}{2}.

$$y=\frac{-4z-128}{27}$$

Whakaoti mō z

$$z=-\frac{27y}{4}-32$$

Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te -4-\frac{3}{2}y.

$$-36-\frac{27}{2}y-2z=28$$

Me tāpiri te 36 ki ngā taha e rua.

$$-\frac{27}{2}y-2z=28+36$$

Tāpirihia te 28 ki te 36, ka 64.

$$-\frac{27}{2}y-2z=64$$

Me tāpiri te \frac{27}{2}y ki ngā taha e rua.

$$-2z=64+\frac{27}{2}y$$

He hanga arowhānui tō te whārite.

$$-2z=\frac{27y}{2}+64$$

Whakawehea ngā taha e rua ki te -2.

$$\frac{-2z}{-2}=\frac{\frac{27y}{2}+64}{-2}$$

Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.

$$z=\frac{\frac{27y}{2}+64}{-2}$$

Whakawehe 64+\frac{27y}{2} ki te -2.

$$z=-\frac{27y}{4}-32$$
