Whakaoti i te x+7=3(x-32)

$$x+7=3(x-32)$$

Whakaoti mō x

$$x = \frac{103}{2} = 51\frac{1}{2} = 51.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-32.

$$x+7=3x-96$$

Tangohia te 3x mai i ngā taha e rua.

$$x+7-3x=-96$$

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

$$-2x+7=-96$$

Tangohia te 7 mai i ngā taha e rua.

$$-2x=-96-7$$

Tangohia te 7 i te -96, ka -103.

$$-2x=-103$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{-103}{-2}$$

Ka taea te hautanga \frac{-103}{-2} te whakamāmā ki te \frac{103}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{103}{2}$$
