So your answer would be x-19+0. Let x represent the original price of the stock.
Quarter is $0.25
Dollar is just $1
x is amount of quarters
y is amount of dollar coins
Two equations we know
0.25x+1y=10.75 and
x+y=22
solve both for y
0.25x+1y=10.75
y=10.75-0.25x
x+y=22
y=22-x
set them equal
22-x= (y) =10.75-0.25x
11.25=0.75x
x=15 quarters
then put x=15 into either equation and now solve for y
x+y=22
15+y=22
y=7 dollar coins
