6 0

8 ÷ (7 - 9) * ( 4 + (-4) ) <--- notice that bolded part.

4 + (-4) = 4 - 4 = 0.

after that, you're pretty much dividing and multiplying by 0, so

whatever ÷ whatever * whatever * 0 = 0.

Hello anyone to help ​
Murljashka [212]

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
