Luis Marks · Answer 1

3x = [ (6*6) + 540] : 8

To simplify this, you must first multiply what is in the parenthesis.

3x = [ (36) + 540] : 8

Now, you have to add what is in the brackets.

3x = 576 : 8

Divide

3x = 72

Divide both sides by 3 to solve for x

x = 24

In the example I gave (it's an original example, I did not copy from anywhere), the 36 and 540 are added together before being divided by 8. If the brackets were not there, 540 would have been divided by 8 and then added to 36 because of pemdas, which would have given us a completely different answer.
