Whakaoti i te M=5-5/10+x

$$M = \frac { 5 - 5 } { 10 + x }$$

Whakaoti mō x

$$x\neq -10$$

$$M=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -10 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+10.

$$M\left(x+10\right)=5-5$$

Whakamahia te āhuatanga tohatoha hei whakarea te M ki te x+10.

$$Mx+10M=5-5$$

Tangohia te 5 i te 5, ka 0.

$$Mx+10M=0$$

Tangohia te 10M mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$Mx=-10M$$

Whakawehea ngā taha e rua ki te M.

$$\frac{Mx}{M}=-\frac{10M}{M}$$

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

$$x=-\frac{10M}{M}$$

Whakawehe -10M ki te M.

$$x=-10$$

Tē taea kia ōrite te tāupe x ki -10.

$$x\in \emptyset$$

Whakaoti mō M

$$M=0$$

$$x\neq -10$$
