Answer:
y= -3x-40
Step-by-step explanation:
first distribute
y+10= -3x-30
than subtract 10
y= -3x-40
The x intercept represents the maximum number of books he can buy
All you have to do for this one is 650 divided by 76 which is 8 but it won't go into it evenly
+8y and -8y cross out.
So the first one is 3x=15
Second one is 2x=10
x=5
Then plug x is one of the equations
2(5)-8y=10
10-8y=10
x=5
y=0
