Whakaoti i te 9(x-3)-5(x-1)quadquadquad=-9

$$9 ( x - 3 ) - 5 ( x - 1 ) \quad \quad \quad = - 9$$

Whakaoti mō x

$$x = \frac{13}{4} = 3\frac{1}{4} = 3.25$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x-3.

$$9x-27-5\left(x-1\right)=-9$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-1.

$$9x-27-5x+5=-9$$

Pahekotia te 9x me -5x, ka 4x.

$$4x-27+5=-9$$

Tāpirihia te -27 ki te 5, ka -22.

$$4x-22=-9$$

Me tāpiri te 22 ki ngā taha e rua.

$$4x=-9+22$$

Tāpirihia te -9 ki te 22, ka 13.

$$4x=13$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{13}{4}$$
