Question

K=5r-11s solve for r
​

Answer 1

`r=(k+11s)/(5)`

Explanation:

`k=5r-11s`

Add 11s on both sides.

`k+11s=5r-11s+11s`

`k+11s=5r`

Divide both sides by 5.

`(k+11s)/(5) =(5r)/(5)`

`(k+11s)/(5) =r`

Answer 2

11s + k

r = ------------

5

Explanation:

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:

11s + k

r = ------------

5
