Whakaoti i te -(-5s-5)+8(s-5)=0

$$- ( - 5 s - 5 ) + 8 ( s - 5 ) = 0$$

Whakaoti mō s

$$s = \frac{35}{13} = 2\frac{9}{13} \approx 2.692307692$$

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

$$-\left(-5s\right)-\left(-5\right)+8\left(s-5\right)=0$$

Ko te tauaro o -5s ko 5s.

$$5s-\left(-5\right)+8\left(s-5\right)=0$$

Ko te tauaro o -5 ko 5.

$$5s+5+8\left(s-5\right)=0$$

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te s-5.

$$5s+5+8s-40=0$$

Pahekotia te 5s me 8s, ka 13s.

$$13s+5-40=0$$

Tangohia te 40 i te 5, ka -35.

$$13s-35=0$$

Me tāpiri te 35 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$13s=35$$

Whakawehea ngā taha e rua ki te 13.

$$s=\frac{35}{13}$$
