Whakaoti i te s+3=7(s+3)-(8-5s)

$$s + 3 = 7 ( s + 3 ) - ( 8 - 5 s )$$

Whakaoti mō s

$$s=-\frac{10}{11}\approx -0.909090909$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te s+3.

$$s+3=7s+21-\left(8-5s\right)$$

Hei kimi i te tauaro o 8-5s, kimihia te tauaro o ia taurangi.

$$s+3=7s+21-8-\left(-5s\right)$$

Ko te tauaro o -5s ko 5s.

$$s+3=7s+21-8+5s$$

Tangohia te 8 i te 21, ka 13.

$$s+3=7s+13+5s$$

Pahekotia te 7s me 5s, ka 12s.

$$s+3=12s+13$$

Tangohia te 12s mai i ngā taha e rua.

$$s+3-12s=13$$

Pahekotia te s me -12s, ka -11s.

$$-11s+3=13$$

Tangohia te 3 mai i ngā taha e rua.

$$-11s=13-3$$

Tangohia te 3 i te 13, ka 10.

$$-11s=10$$

Whakawehea ngā taha e rua ki te -11.

$$s=\frac{10}{-11}$$

Ka taea te hautanga \frac{10}{-11} te tuhi anō ko -\frac{10}{11} mā te tango i te tohu tōraro.

$$s=-\frac{10}{11}$$
