Question

What is the value of s in the equation 3r=10+5s when r =10

Answer 1

s=4

Explanation:

3(10)=10+5s

30=10+5s

Answer 2

s = 4

Explanation:

Given

3r = 10 + 5s ← substitute r = 10

3 × 10 = 10 + 5s

30 = 10 + 5s ( subtract 10 from both sides )

20 = 5s ( divide both sides by 5 )

4 = s
