Whakaoti i te 2left(2+xright)-6-7x=13x-1+4x

$$2 \left( 2+x \right) -6-7x = 13x-1+4x$$

Whakaoti mō x

$$x=-\frac{1}{22}\approx -0.045454545$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$4+2x-6-7x=13x-1+4x$$

Tangohia te 6 i te 4, ka -2.

$$-2+2x-7x=13x-1+4x$$

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

$$-2-5x=13x-1+4x$$

Pahekotia te 13x me 4x, ka 17x.

$$-2-5x=17x-1$$

Tangohia te 17x mai i ngā taha e rua.

$$-2-5x-17x=-1$$

Pahekotia te -5x me -17x, ka -22x.

$$-2-22x=-1$$

Me tāpiri te 2 ki ngā taha e rua.

$$-22x=-1+2$$

Tāpirihia te -1 ki te 2, ka 1.

$$-22x=1$$

Whakawehea ngā taha e rua ki te -22.

$$x=\frac{1}{-22}$$

Ka taea te hautanga \frac{1}{-22} te tuhi anō ko -\frac{1}{22} mā te tango i te tohu tōraro.

$$x=-\frac{1}{22}$$
