Whakaoti i te m+x+2=73-x

$$m + x + 2 = 73 - x$$

Whakaoti mō m

$$m=71-2x$$

Ngā Upane Otinga

Tangohia te x mai i ngā taha e rua.

$$m+2=73-x-x$$

Pahekotia te -x me -x, ka -2x.

$$m+2=73-2x$$

Tangohia te 2 mai i ngā taha e rua.

$$m=73-2x-2$$

Tangohia te 2 i te 73, ka 71.

$$m=71-2x$$

Whakaoti mō x

$$x=\frac{71-m}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te x ki ngā taha e rua.

$$m+x+2+x=73$$

Pahekotia te x me x, ka 2x.

$$m+2x+2=73$$

Tangohia te m mai i ngā taha e rua.

$$2x+2=73-m$$

Tangohia te 2 mai i ngā taha e rua.

$$2x=73-m-2$$

Tangohia te 2 i te 73, ka 71.

$$2x=71-m$$

Whakawehea ngā taha e rua ki te 2.

$$\frac{2x}{2}=\frac{71-m}{2}$$

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

$$x=\frac{71-m}{2}$$
