Question

solve for s.
0.8 + s = 9(0.2s + 0.8)
s =

Explanation:

Step1: Expand the right - hand side

$0.8 + s=9\times0.2s + 9\times0.8$
$0.8 + s = 1.8s+7.2$

Step2: Move terms with s to one side

$s-1.8s=7.2 - 0.8$

Step3: Combine like terms

$-0.8s=6.4$

Step4: Solve for s

$s=\frac{6.4}{- 0.8}$
$s=-8$

Answer:

$-8$
