Answer:

a=-39; s=0.75

Explanation:

Solve the System of Equations by Substitution.

First, solve one of the equations for a variable. I'll do the 2nd one because it only has one variable.

a+24=-15 -------> a=-39

Now we know what a is just plug it back into the other equation and get s.


(a-3)/(7s) =-8


(-39-3)/(7s) =-8


(-42)/(7s) =-8

Switch the -8 and 7s


(-42)/(-8) =7s

Simplify the fraction

5.25=7s

Divide by 7 to isolate the s

0.75=s
