You can put this solution on YOUR website! Since the absolute value is a grouping symbol, like parentheses, you have to calculate it first ,
but within the absolute value you multiply first to find the product of 4 times (-2), because multiplication has priority over addition and subtraction.
After this point, multiplying 4 times (-6) must be done before subtracting 6, so
If your teacher objects to having more than one equal sign on a line, just do it your teacher's way.
