Whakaoti i te 2(x-1)+3(x+4)=x+3

$$2 ( x - 1 ) + 3 ( x + 4 ) = x + 3$$

Whakaoti mō x

$$x = -\frac{7}{4} = -1\frac{3}{4} = -1.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.

$$2x-2+3\left(x+4\right)=x+3$$

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

$$2x-2+3x+12=x+3$$

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

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

Tāpirihia te -2 ki te 12, ka 10.

$$5x+10=x+3$$

Tangohia te x mai i ngā taha e rua.

$$5x+10-x=3$$

Pahekotia te 5x me -x, ka 4x.

$$4x+10=3$$

Tangohia te 10 mai i ngā taha e rua.

$$4x=3-10$$

Tangohia te 10 i te 3, ka -7.

$$4x=-7$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{-7}{4}$$

Ka taea te hautanga \frac{-7}{4} te tuhi anō ko -\frac{7}{4} mā te tango i te tohu tōraro.

$$x=-\frac{7}{4}$$
