Whakaoti i te 2(x+6)-7x=3x-5x+8

$$2 ( x + 6 ) - 7 x = 3 x - 5 x + 8$$

Whakaoti mō x

$$x = \frac{4}{3} = 1\frac{1}{3} \approx 1.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+6.

$$2x+12-7x=3x-5x+8$$

Pahekotia te 2x me -7x, ka -5x.

$$-5x+12=3x-5x+8$$

Pahekotia te 3x me -5x, ka -2x.

$$-5x+12=-2x+8$$

Me tāpiri te 2x ki ngā taha e rua.

$$-5x+12+2x=8$$

Pahekotia te -5x me 2x, ka -3x.

$$-3x+12=8$$

Tangohia te 12 mai i ngā taha e rua.

$$-3x=8-12$$

Tangohia te 12 i te 8, ka -4.

$$-3x=-4$$

Whakawehea ngā taha e rua ki te -3.

$$x=\frac{-4}{-3}$$

Ka taea te hautanga \frac{-4}{-3} te whakamāmā ki te \frac{4}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{4}{3}$$
