Dear Tyler,

This is a common Algerbra problem. You would start by solving the problem inside the parenthesis first. Then, add the answer to 7. Finally, use addition to finalize the equation so both sides are equal.

Good Luck!

Hi Tyler,

To simplify this problem you would start by solving what is inside the parentheses. So:

- (33 + 45) + 7 = 78 + 7

Now that we have solved what was inside the parentheses and removed the parentheses the problem is now simple addition.

Hope this helps.

*This kind of problem requires to use associative and commutative properties of addition.
*

*a + b + c = (a + b) + c = a + (b + c) *

*a + b = b + c*

**~~~~~~~~~~~**

(33 + 45) + 7 =

33 + 45 + 7 =

45 + 33 + 7 =

45 + (33 + 7) =

45 + 40 = **85 **
