Whakaoti i te 0.8*(y-1)+x=0.875+(x-1)

$$0.8 \times ( y - 1 ) + x = 0.875 + ( x - 1 )$$

Whakaoti mō y

$$y=0.84375$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 0.8 ki te y-1.

$$0.8y-0.8+x=0.875+x-1$$

Tangohia te 1 i te 0.875, ka -0.125.

$$0.8y-0.8+x=-0.125+x$$

Me tāpiri te 0.8 ki ngā taha e rua.

$$0.8y+x=-0.125+x+0.8$$

Tāpirihia te -0.125 ki te 0.8, ka 0.675.

$$0.8y+x=0.675+x$$

Tangohia te x mai i ngā taha e rua.

$$0.8y=0.675+x-x$$

Pahekotia te x me -x, ka 0.

$$0.8y=0.675$$

Whakawehea ngā taha e rua ki te 0.8.

$$y=\frac{0.675}{0.8}$$

Whakarohaina te \frac{0.675}{0.8} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$y=\frac{675}{800}$$

Whakahekea te hautanga \frac{675}{800} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$y=\frac{27}{32}$$

Whakaoti mō x (complex solution)

$$x\in \mathrm{C}$$

$$y = \frac{27}{32} = 0.84375$$

Whakaoti mō x

$$x\in \mathrm{R}$$

$$y = \frac{27}{32} = 0.84375$$
