The answer is no real solutions (x ∉ R) because a perfect square cannot be negative.
Answer:
32
Step-by-step explanation:
let b represent the number of blue marbles then
yellow = 5b + 7 and
b + 5b + 7 = 37, that is
6b + 7 = 37 ( subtract 7 from both sides )
6b = 30 ( divide both sides by 6 )
b = 5
Thus there are 5 blue and 5(5) + 7 = 25 + 7 = 32 yellow marbles

9x-30 I’m pretty sure!
We are finding the difference, which means subtract! Nine times a number would be 9x and since it’s difference you would subtract it by 30.
