Whakaoti i te xy-5x+2y=0

$$x y - 5 x + 2 y = 0$$

Whakaoti mō x

$$x=-\frac{2y}{y-5}$$

$$y\neq 5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$xy-5x=-2y$$

Pahekotia ngā kīanga tau katoa e whai ana i te x.

$$\left(y-5\right)x=-2y$$

Whakawehea ngā taha e rua ki te y-5.

$$\frac{\left(y-5\right)x}{y-5}=-\frac{2y}{y-5}$$

Mā te whakawehe ki te y-5 ka wetekia te whakareanga ki te y-5.

$$x=-\frac{2y}{y-5}$$

Whakaoti mō y

$$y=\frac{5x}{x+2}$$

$$x\neq -2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te 5x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$xy+2y=5x$$

Pahekotia ngā kīanga tau katoa e whai ana i te y.

$$\left(x+2\right)y=5x$$

Whakawehea ngā taha e rua ki te x+2.

$$\frac{\left(x+2\right)y}{x+2}=\frac{5x}{x+2}$$

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

$$y=\frac{5x}{x+2}$$
