Question

25 = 13 – 4s
What is the answer

Answer 1

s = -3

Explanation:

Better to say, "Solve 25 = 13 - 4s for s." "Answer" is too general.

Starting with 25 = 13 - 4s, subtract 13 from both sides, to isolate -4s:

12 = -4s, or s = -12/4, or s = -3

Answer 2

Answer: s = -3

Explanation:

25 = 13 - 4s

-13 -13

--------------------

12 = -4s

12/-4 = -4/-4

-------------------

-3 = s
