Whakaoti i te 3-m/m+2=2

$$\frac { 3 - m } { m + 2 } = 2$$

Whakaoti mō m

$$m=-\frac{1}{3}\approx -0.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe m ki -2 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te m+2.

$$3-m=2\left(m+2\right)$$

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

$$3-m=2m+4$$

Tangohia te 2m mai i ngā taha e rua.

$$3-m-2m=4$$

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

$$3-3m=4$$

Tangohia te 3 mai i ngā taha e rua.

$$-3m=4-3$$

Tangohia te 3 i te 4, ka 1.

$$-3m=1$$

Whakawehea ngā taha e rua ki te -3.

$$m=\frac{1}{-3}$$

Ka taea te hautanga \frac{1}{-3} te tuhi anō ko -\frac{1}{3} mā te tango i te tohu tōraro.

$$m=-\frac{1}{3}$$
