Answer:
[tex]r=\frac{k+11s}{5}[/tex]
Step-by-step explanation:
[tex]k=5r-11s[/tex]
Add 11s on both sides.
[tex]k+11s=5r-11s+11s[/tex]
[tex]k+11s=5r[/tex]
Divide both sides by 5.
[tex]\frac{k+11s}{5} =\frac{5r}{5}[/tex]
[tex]\frac{k+11s}{5} =r[/tex]
11s + k
r = ------------
5
k=5r-11s needs to be manipulated so that the 5r term is isolated / alone.
Adding 11s to both sides, we get:
5r = 11s + k
and then dividing all three terms by 5 yields:
