Question

Daeja and Juana solved this equation 6 = 1/2s.

Daeja: The solution is s = 12.
Juana: The solution is s = 3.

Who is correct?

Explain how you know.

Answer 1

Daeja is correct.

Explanation:

Equation: 6 = 1/2s

Solve:

(2)6 = 1/2s(2) <== multiply both sides by 2

12 = s or s = 12

Therefore, Daeja is correct.

I multiplied both sides by 2 to isolate s, and 2 ⋅ 6 is 12.

Hope this helps!
