Answer: You bought 7 books and you also bought 4 magazines
Explanation:
x = # of books purchased
y = # of magazines purchased
System of equations:
8x + 5y = 76
x + y = 11
Let’s use elimination in this case, but substitution can also work.
8x + 5y = 76
Multiply the (x + y = 11) by -8
We get:
8x + 5y = 76
-8x - 8y = -88
The xs cancel.
Add like terms.
-3y = -12
Divide by -3 on both sides
y = 4
Now plug in 4 into the (x + y = 11) equation to get x.
x + (4) = 11
Subtract 4 on both sides
x = 7
Answer:
b+m = 11
8b + 5m = 76
b = 11-m
substitute
8(11-m)+5m = 76
88 - 8m + 5m = 76
12 = 3m
4 = m 7 = b
check
4*5 + 7*8 ?=? 76
20 + 56 = 76 the answer is correct.
