Whakaoti i te w-7y+16x-80=0

$$w - 7 y + 16 x - 80 = 0$$

Whakaoti mō w

$$w=80+7y-16x$$

Ngā Upane Otinga

Me tāpiri te 7y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$w+16x-80=7y$$

Tangohia te 16x mai i ngā taha e rua.

$$w-80=7y-16x$$

Me tāpiri te 80 ki ngā taha e rua.

$$w=7y-16x+80$$

Whakaoti mō x

$$x=\frac{7y}{16}-\frac{w}{16}+5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$-7y+16x-80=-w$$

Me tāpiri te 7y ki ngā taha e rua.

$$16x-80=-w+7y$$

Me tāpiri te 80 ki ngā taha e rua.

$$16x=-w+7y+80$$

He hanga arowhānui tō te whārite.

$$16x=7y-w+80$$

Whakawehea ngā taha e rua ki te 16.

$$\frac{16x}{16}=\frac{7y-w+80}{16}$$

Mā te whakawehe ki te 16 ka wetekia te whakareanga ki te 16.

$$x=\frac{7y-w+80}{16}$$

Whakawehe -w+7y+80 ki te 16.

$$x=\frac{7y}{16}-\frac{w}{16}+5$$
