Whakaoti i te 6-4(x-3)=3x-5(x-5)

$$6-4(x-3)=3x-5(x-5)$$

Whakaoti mō x

$$x = -\frac{7}{2} = -3\frac{1}{2} = -3.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-3.

$$6-4x+12=3x-5\left(x-5\right)$$

Tāpirihia te 6 ki te 12, ka 18.

$$18-4x=3x-5\left(x-5\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-5.

$$18-4x=3x-5x+25$$

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

$$18-4x=-2x+25$$

Me tāpiri te 2x ki ngā taha e rua.

$$18-4x+2x=25$$

Pahekotia te -4x me 2x, ka -2x.

$$18-2x=25$$

Tangohia te 18 mai i ngā taha e rua.

$$-2x=25-18$$

Tangohia te 18 i te 25, ka 7.

$$-2x=7$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{7}{-2}$$

Ka taea te hautanga \frac{7}{-2} te tuhi anō ko -\frac{7}{2} mā te tango i te tohu tōraro.

$$x=-\frac{7}{2}$$
