Answer:
1
Step-by-step explanation:
Substitute the value of the variable into the expression and simplify.
4-2-1=1
0.69x+4.32=0.46x+3.4
-3.4 -3.4
____________________
0.69x+0.92=0.46x
-0.69x -0.69x
______________
0.92=-0.23
multiply by -100/23 multiply by -100/23
x=-4
Pretty simple equation, where we need to find the number of books. If it is 2$ each day per book
72/9 = 8$ per day is the late fee paid

So equation is
“# books = (amount paid)/(days * per day payment)”
