Whakaoti i te 13-x=x+2

$$13-x = x+2$$

Whakaoti mō x

$$x = \frac{11}{2} = 5\frac{1}{2} = 5.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te x mai i ngā taha e rua.

$$13-x-x=2$$

Pahekotia te -x me -x, ka -2x.

$$13-2x=2$$

Tangohia te 13 mai i ngā taha e rua.

$$-2x=2-13$$

Tangohia te 13 i te 2, ka -11.

$$-2x=-11$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{-11}{-2}$$

Ka taea te hautanga \frac{-11}{-2} te whakamāmā ki te \frac{11}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{11}{2}$$
