Whakaoti i te 3(-1-x)=9+(1+2x)

$$3(-1-x)=9+(1+2x)$$

Whakaoti mō x

$$x = -\frac{13}{5} = -2\frac{3}{5} = -2.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te -1-x.

$$-3-3x=9+1+2x$$

Tāpirihia te 9 ki te 1, ka 10.

$$-3-3x=10+2x$$

Tangohia te 2x mai i ngā taha e rua.

$$-3-3x-2x=10$$

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

$$-3-5x=10$$

Me tāpiri te 3 ki ngā taha e rua.

$$-5x=10+3$$

Tāpirihia te 10 ki te 3, ka 13.

$$-5x=13$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{13}{-5}$$

Ka taea te hautanga \frac{13}{-5} te tuhi anō ko -\frac{13}{5} mā te tango i te tohu tōraro.

$$x=-\frac{13}{5}$$
