Whakaoti i te 0.09x+0.095y=783

$$0.09 x + 0.095 y = 783$$

Whakaoti mō x

$$x=-\frac{19y}{18}+8700$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 0.095y mai i ngā taha e rua.

$$0.09x=783-0.095y$$

He hanga arowhānui tō te whārite.

$$0.09x=-\frac{19y}{200}+783$$

Whakawehea ngā taha e rua o te whārite ki te 0.09, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{0.09x}{0.09}=\frac{-\frac{19y}{200}+783}{0.09}$$

Mā te whakawehe ki te 0.09 ka wetekia te whakareanga ki te 0.09.

$$x=\frac{-\frac{19y}{200}+783}{0.09}$$

Whakawehe 783-\frac{19y}{200} ki te 0.09 mā te whakarea 783-\frac{19y}{200} ki te tau huripoki o 0.09.

$$x=-\frac{19y}{18}+8700$$

Whakaoti mō y

$$y=\frac{156600-18x}{19}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 0.09x mai i ngā taha e rua.

$$0.095y=783-0.09x$$

He hanga arowhānui tō te whārite.

$$0.095y=-\frac{9x}{100}+783$$

Whakawehea ngā taha e rua o te whārite ki te 0.095, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{0.095y}{0.095}=\frac{-\frac{9x}{100}+783}{0.095}$$

Mā te whakawehe ki te 0.095 ka wetekia te whakareanga ki te 0.095.

$$y=\frac{-\frac{9x}{100}+783}{0.095}$$

Whakawehe 783-\frac{9x}{100} ki te 0.095 mā te whakarea 783-\frac{9x}{100} ki te tau huripoki o 0.095.

$$y=\frac{156600-18x}{19}$$
