Whakaoti i te x+(3y+5)+2z=215

$$x + ( 3 y + 5 ) + 2 z = 215$$

Whakaoti mō x

$$x=210-2z-3y$$

Ngā Upane Otinga

Tangohia te 3y mai i ngā taha e rua.

$$x+5+2z=215-3y$$

Tangohia te 5 mai i ngā taha e rua.

$$x+2z=215-3y-5$$

Tangohia te 5 i te 215, ka 210.

$$x+2z=210-3y$$

Tangohia te 2z mai i ngā taha e rua.

$$x=210-3y-2z$$

Whakaoti mō y

$$y=-\frac{x}{3}-\frac{2z}{3}+70$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te x mai i ngā taha e rua.

$$3y+5+2z=215-x$$

Tangohia te 5 mai i ngā taha e rua.

$$3y+2z=215-x-5$$

Tangohia te 5 i te 215, ka 210.

$$3y+2z=210-x$$

Tangohia te 2z mai i ngā taha e rua.

$$3y=210-x-2z$$

He hanga arowhānui tō te whārite.

$$3y=210-2z-x$$

Whakawehea ngā taha e rua ki te 3.

$$\frac{3y}{3}=\frac{210-2z-x}{3}$$

Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.

$$y=\frac{210-2z-x}{3}$$

Whakawehe 210-x-2z ki te 3.

$$y=-\frac{x}{3}-\frac{2z}{3}+70$$
