Question

2. y= 22 + 9 and y-9= 2x both correctly

describe blueberries given and returned. If you
know you have 5 blueberries to give, and want
to know how many are returned, which
equation is more efficient?

Answer 1

y-9=2x

Explanation:

The reason it is y-9=2x is because y=22+9 is y=31 and you have 5 to give so 5=31 which is not correct.

Hope this helps!
