Which of the following best describes the solution to the equation below?

2 (b+3) + 2b=26

A) infinite solutions

B) no solution

C) exactly one solution who is b=7

D) exactly one solution which is b=5

D) One solution. b=5

Distribute 2 times b plus 2 times 3

2b+6

2b+6+2b=26

Combine like terms 4b+6=26

Subtract 6 from both sides

4b=20

Divide both sides by 4

b=5

Check by substituting 5 for b

2 (5+3) + 2 (5) = 26

2 (8) + 2 (5) = 26

16+10=26

26=26
