Question

How would I solve this question? I need to solve for s.​

Answer 1

4

Explanation:

• 2r = 5s/2 - s/4 ⇒ bring to common denominator
• 2r = 10s/4 - s/4
• 2r = 9s/4
• 9s = 8r ⇒ multiply both sides by 4
• s = 8r/9 ⇒ divide both sides by 9
• s = 8/9*9/2 ⇒ replace r with 9/2, simplify
• s = 4 ⇒ answer
