Question

Solve for r 2=4r+s whats r

Answer 1

`(2-s)/(4)=r`

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

`(2-s)/(4)=r`

Answer 2

the answer is r = 1/2 - s/4
