You use the order of operations. So in you start with multiplication. 8*7= 56. Then that would leave 56-4. 56-4 is 52.
Not Specific Enough:
is it 4a(2-3a)-41(7a-72)-23a(64)6a-2?

Answer:
17
Step-by-step explanation:
2y+2=36
Let's solve this equation for 2y first. This means get 2y by itself.
So to get 2y by itself I need to undo that addition of 2 next to it.
The inverse operation of addition is subtraction.
I'm going to subtract 2 on both sides:
2y =36-2
2y =34
Now we want to get y by itself so we divide both sides by 2 since division and multiplication are inverse operations:
y= 34/2
y= 17
