Question 1181624: Two students both solved the equation -4x-0.5=6 incorrectly. The work of each student is shown.
Student A's Work:
-4x-0.5=6 | Step 1: -4x-2=6|Step 2: -4x=8S|tep 3: x=-2

Student B's Work:
-4x-0.5=6 | Step 1: -4x+2=6|Step 2: -4x=8|Step 3: x=-2

In which step of their work did Student A and Student B make their first mistake?
A. Student A made their first mistake in Step 1 and Student B made their first mistake in Step 1.
B. Student A made their first mistake in Step 1 and Student B made their first mistake in Step 2.
C. Student A made their first mistake in Step 2 and Student B made their first mistake in Step 1.
D.Student A made their first mistake in Step 2 and Student B made their first mistake in Step 2.
Is it A, B, C, or D?

Student A's Work:
-4x-0.5=6+
Step 1:
-4x-2=6 ->first mistake in Step 1 (should be -4x-1%2F2=6)
Step 2:
-4x=8
Step 3:
x=-2
Student B's Work:
-4x-0.5=6
Step 1:
-4x%2B2=6 ->first mistake in Step 1 (should be -4x-1%2F2=6)
Step 2:
-4x=8
Step 3:
x=-2
answer:
A. Student A made their first mistake in Step 1 and Student B made their first mistake in Step 1.
