Whakaoti i te -0.77x+0.64x/0.25-y*10=0

$$-0.77x+ \frac{ 0.64x }{ 0.25 } -y \times 10=0$$

Whakaoti mō x

$$x=\frac{1000y}{179}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea te 0.64x ki te 0.25, kia riro ko 2.56x.

$$-0.77x+2.56x-y\times 10=0$$

Pahekotia te -0.77x me 2.56x, ka 1.79x.

$$1.79x-y\times 10=0$$

Me tāpiri te y\times 10 ki ngā taha e rua.

$$1.79x=0+y\times 10$$

Ko te tau i tāpiria he kore ka hua koia tonu.

$$1.79x=y\times 10$$

He hanga arowhānui tō te whārite.

$$1.79x=10y$$

Whakawehea ngā taha e rua o te whārite ki te 1.79, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{1.79x}{1.79}=\frac{10y}{1.79}$$

Mā te whakawehe ki te 1.79 ka wetekia te whakareanga ki te 1.79.

$$x=\frac{10y}{1.79}$$

Whakawehe 10y ki te 1.79 mā te whakarea 10y ki te tau huripoki o 1.79.

$$x=\frac{1000y}{179}$$

Whakaoti mō y

$$y=\frac{179x}{1000}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea te 0.64x ki te 0.25, kia riro ko 2.56x.

$$-0.77x+2.56x-y\times 10=0$$

Pahekotia te -0.77x me 2.56x, ka 1.79x.

$$1.79x-y\times 10=0$$

Whakareatia te -1 ki te 10, ka -10.

$$1.79x-10y=0$$

Tangohia te 1.79x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-10y=-1.79x$$

He hanga arowhānui tō te whārite.

$$-10y=-\frac{179x}{100}$$

Whakawehea ngā taha e rua ki te -10.

$$\frac{-10y}{-10}=-\frac{\frac{179x}{100}}{-10}$$

Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.

$$y=-\frac{\frac{179x}{100}}{-10}$$

Whakawehe -\frac{179x}{100} ki te -10.

$$y=\frac{179x}{1000}$$
