Answer 1

Let the number of blue markers be b, and let the number of red markers be r.

"The number of blue markers in a drawer is 4 more than twice the number of red markers."

means that: b = 4 + 2r because:


""The number of blue markers." : b
"is" : =
"4 more than" : +4
"twice the number of red markers": 2r



Answer: b = 4 + 2r
