Whakaoti i te 7(x+9)=4(x-8)

$$7 ( x + 9 ) = 4 ( x - 8 )$$

Whakaoti mō x

$$x = -\frac{95}{3} = -31\frac{2}{3} \approx -31.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te x+9.

$$7x+63=4\left(x-8\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-8.

$$7x+63=4x-32$$

Tangohia te 4x mai i ngā taha e rua.

$$7x+63-4x=-32$$

Pahekotia te 7x me -4x, ka 3x.

$$3x+63=-32$$

Tangohia te 63 mai i ngā taha e rua.

$$3x=-32-63$$

Tangohia te 63 i te -32, ka -95.

$$3x=-95$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{-95}{3}$$

Ka taea te hautanga \frac{-95}{3} te tuhi anō ko -\frac{95}{3} mā te tango i te tohu tōraro.

$$x=-\frac{95}{3}$$
