Ok so the question has already been answered by someone but i wanna give you some advice... it’s called ✨photomath✨ and you can take a picture of the problem or type it in... it would have been able to solve this equation right away, so you wouldn’t have had to wait for someone to answer. have a great day :)
R + b = 21
2b = r
now we sub eq 2 into eq 1
r + b = 21
2b + b = 21
3b = 21
b = 21/3
b = 7
2b = r
2(7) = r
14 = r
so there are 7 bluejays (b) and 14 robins (r)...for a total of 21
