Question

2r=5s/2-s/4 (solve for s)

Answer 1

• Calculate the product
2r = 5s/2 - s/4
• multiply both sides by 4
8r = 10s - s
• collect like terms
8r = 9s
• divide both sides by 9
8r ➗ 9 = 9s
• write the value of s
s = 8/9

Answer 2

s=8r/9

Explanation:

2r=5s/2-s/4 multiply both sides by 4

8r=10s-s (5s times 4 = 20s and 20s/2=10s) combine like terms

8r=9s divide by 9 to isolate s

8r/9=s
