Whakaoti i te x*18/x+56=22

$$\frac { x \cdot 18 } { x + 56 } = 22$$

Whakaoti mō x

$$x=-308$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -56 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+56.

$$x\times 18=22\left(x+56\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 22 ki te x+56.

$$x\times 18=22x+1232$$

Tangohia te 22x mai i ngā taha e rua.

$$x\times 18-22x=1232$$

Pahekotia te x\times 18 me -22x, ka -4x.

$$-4x=1232$$

Whakawehea ngā taha e rua ki te -4.

$$x=\frac{1232}{-4}$$

Whakawehea te 1232 ki te -4, kia riro ko -308.

$$x=-308$$
