Whakaoti i te 4.5x-100y=0

$$4.5x-100y=0$$

Whakaoti mō x

$$x=\frac{200y}{9}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te 100y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$4.5x=100y$$

Whakawehea ngā taha e rua o te whārite ki te 4.5, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{4.5x}{4.5}=\frac{100y}{4.5}$$

Mā te whakawehe ki te 4.5 ka wetekia te whakareanga ki te 4.5.

$$x=\frac{100y}{4.5}$$

Whakawehe 100y ki te 4.5 mā te whakarea 100y ki te tau huripoki o 4.5.

$$x=\frac{200y}{9}$$

Whakaoti mō y

$$y=\frac{9x}{200}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 4.5x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-100y=-4.5x$$

He hanga arowhānui tō te whārite.

$$-100y=-\frac{9x}{2}$$

Whakawehea ngā taha e rua ki te -100.

$$\frac{-100y}{-100}=-\frac{\frac{9x}{2}}{-100}$$

Mā te whakawehe ki te -100 ka wetekia te whakareanga ki te -100.

$$y=-\frac{\frac{9x}{2}}{-100}$$

Whakawehe -\frac{9x}{2} ki te -100.

$$y=\frac{9x}{200}$$
