Answer 1

Answer:

5s-8 = 0  

Add  8  to both sides of the equation :  

                     5s = 8

Divide both sides of the equation by 5:

                    s = 8/5 = 1.600

Step-by-step explanation:

it was difficult and too much wording

Answer 2

Answer:

7

Step-by-step explanation:

$9-\frac{8}{S} \\S=4$

Substitute the value of S into the expression:

$9-\frac{8}{4}$

Simplify the fraction by dividing the numerator and denominator by 4:

$9-\frac{8/4}{4/4} \\\\9-\frac{2}{1}$

Simplify :

$9-2$

Solve with subtraction:

$9-2=7$

Finito.
