Let the price of single algebra book = x
and the price of geometry book = y
Then equation (1) = 2x+3y=34
3y= (34 - 2x)
y= (34 - 2x)/3
And equation (2) = 3x + 2y=36
put value of y in equation (2)
3x + 2 (34-2x)/3= 36
9x + 2 (34-2x)=108
9x + 68 - 4x=108
5x=40
x=8
put x=8 in equation ( 1 )
2(8) + 3y= 34
16+3y=34
3y=18
y=6
Hence, price of algebra book = 8$ and price of geometry book=6$
Ur answer is d !!! Good luck
I think it means that they were ready to prove it no matter what it took but not really sure since I haven’t read the whole story
