Question

A student is attempting to isolate the variable s in the literal equation below. Which statement best applies to the sample mathematical work shown?
Given: st + s – 3 = 5 – s
Step 1: First, I added s, and then I added 3 to both sides of the equation, resulting in st + 2s = 8.
Step 2: Next, I divided both sides of the equation by s, resulting in t + 2s = 8.
Step 3: Then, I subtracted t from both sides of the equation, resulting in 2s = 8 – t.
Step 4: Finally, I divided both sides of the equation by 2, giving a final answer of.......

Answer 1

s= 8-t / 2

Answer 2

A.
The student failed to add the proper quantity in step 1.
B.
The student failed to divide both sides by s properly in step 2.
C.
The student failed to subtract t from both sides properly in step 3.
D.
The mathematical work is correct as written.

Answer 3

B. The student failed to divide both sides by s properly in step 2.
