Whakaoti i te 5(16-x)=-12(x+7)

$$5(16-x)=-12(x+7)$$

Whakaoti mō x

$$x = -\frac{164}{7} = -23\frac{3}{7} \approx -23.428571429$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 16-x.

$$80-5x=-12\left(x+7\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -12 ki te x+7.

$$80-5x=-12x-84$$

Me tāpiri te 12x ki ngā taha e rua.

$$80-5x+12x=-84$$

Pahekotia te -5x me 12x, ka 7x.

$$80+7x=-84$$

Tangohia te 80 mai i ngā taha e rua.

$$7x=-84-80$$

Tangohia te 80 i te -84, ka -164.

$$7x=-164$$

Whakawehea ngā taha e rua ki te 7.

$$x=\frac{-164}{7}$$

Ka taea te hautanga \frac{-164}{7} te tuhi anō ko -\frac{164}{7} mā te tango i te tohu tōraro.

$$x=-\frac{164}{7}$$
