Answer:
[tex]\frac{2-s}{4}=r[/tex]
Step-by-step explanation:
One solves a literal equation just like a normal algebraic expression with numbers, with inverse operations. Only that with a literal equation, there is a limit to how much one can simplify.
Inverse operations;
2 = 4r + s
-s -s
2 - s = 4r
÷4 ÷4
[tex]\frac{2-s}{4}=r[/tex]
