X²+20-20=4-20
x²=-16
Take the square roots of each side: x=the square root of -16
You cannot do this so there is no solution
However, I'm not perfectly sure, so wait for other answers just in case

Michael is packing books into boxes. Each box can hold either 15 small books or
zavuch27 [327]

Let x equal the number of tiny book boxes and y equal the number of large book boxes.

Because John must pack at least 35 boxes:

(number of tiny book boxes) + (number of large book boxes) = (at least) 35

x + y ≥ 35

 

Since John needs to pack at least 350 books:

 

(number of small books packed) + (number of large books packed) (is at least) 350

(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350

15x + 8y ≥ 350

 

Your system of inequalities is:

 

x + y ≥ 35

15x + 8y ≥ 350
