If 2c + 1 = 11, what is the value of 2c? A. 4
B. 5
C. 10
D. 12

Answers

Answer 1
Answer:

Answer:

2c =10

Explanation:

2c+1-1=11-1          - Subtract 1 from both sides

2c=10                  - Simplify

If you want the value of x you would divide 2 on both sides and you would get 5. But you asked for 2c that's why I gave you 2c.

 Hoped this helped! :)
