Answer:
2 science fiction and 5 mystery
Step-by-step explanation:
First, we will set up a system of equations.
x (science fiction) y (mystery)
x + y = 7 This is the total books bought.
7x + 9y = 59 The amount of each set to the total cost.
Now we solve.
(-7)x + y = 7 equals
-7x - 7y = -49
added to
7x + 9y = 59
this equals
2y = 10
y = 5
Now we know one. We can plug it in to find the other value.
x + 5 = 7
x = 2
