Whakaoti i te 5*4(x+3)=-4(x+3)*-3

$$5 \cdot 4 ( x + 3 ) = - 4 ( x + 3 ) \cdot - 3$$

Whakaoti mō x

$$x=-3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 5 ki te 4, ka 20.

$$20\left(x+3\right)=-4\left(x+3\right)\left(-3\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 20 ki te x+3.

$$20x+60=-4\left(x+3\right)\left(-3\right)$$

Whakareatia te -4 ki te -3, ka 12.

$$20x+60=12\left(x+3\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te x+3.

$$20x+60=12x+36$$

Tangohia te 12x mai i ngā taha e rua.

$$20x+60-12x=36$$

Pahekotia te 20x me -12x, ka 8x.

$$8x+60=36$$

Tangohia te 60 mai i ngā taha e rua.

$$8x=36-60$$

Tangohia te 60 i te 36, ka -24.

$$8x=-24$$

Whakawehea ngā taha e rua ki te 8.

$$x=\frac{-24}{8}$$

Whakawehea te -24 ki te 8, kia riro ko -3.

$$x=-3$$
