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
