Whakaoti i te x+213-3y+y=x

$$x + 213 - 3 y + y = x$$

Whakaoti mō y

$$y = \frac{213}{2} = 106\frac{1}{2} = 106.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te -3y me y, ka -2y.

$$x+213-2y=x$$

Tangohia te x mai i ngā taha e rua.

$$213-2y=x-x$$

Pahekotia te x me -x, ka 0.

$$213-2y=0$$

Tangohia te 213 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-2y=-213$$

Whakawehea ngā taha e rua ki te -2.

$$y=\frac{-213}{-2}$$

Ka taea te hautanga \frac{-213}{-2} te whakamāmā ki te \frac{213}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$y=\frac{213}{2}$$

Whakaoti mō x (complex solution)

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

$$y = \frac{213}{2} = 106\frac{1}{2} = 106.5$$

Whakaoti mō x

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

$$y = \frac{213}{2} = 106\frac{1}{2} = 106.5$$
