Question

Solve 2Q + 5s=r for s and show ALL your steps.

Answer 1

Explanation:

Subtract 2Q from both sides

2Q + 5s − 2Q = r − 2Q

Simplify

5s = r − 2Q

Divide both sides by 5

`(5s)/(5) =(r)/(5) -(20)/(5)`

Simplify

`s=(r-20)/(5)`

Answer 2

2q-r= 5s

divide both sides by 5

2q-r/s =5s/5

therefore S= 2q-r/s
