5x - 2 equivalent to to 2x−2+3x
answer is B. 2x−2+3x
Answer:
I think the answer is 81.
Step-by-step explanation:
Vertical angles are congruent.
x + 3 = 84
- 3 = -3
--------------
x = 81
-4+x=9.5
x=13.5
The student might have subtracted 9.5-4, which results in the answer 5.5. The correct answer is 13.5.
