Question 212747
Simplify:


{{{2x-2(y-2(x+2(2x+3y)))}}}


Step 1.  Work the innermost parenthesis first and then work outward to the next set of parenthesis.


{{{2x-2(y-2(x+4x+6y))}}}


{{{2x-2(y-2(5x+6y))}}}


{{{2x-2(y-10x-12y)}}}


{{{2x-2(-10x-11y)}}}


{{{2x-(-20x-22y)}}}
 

{{{2x+20x+22y}}}


{{{22x+22y}}}


Step 3.  Factor out 22


{{{22(x+y)}}}


Step 4.   ANSWER:   22(x+y) or 22x+22y


I hope the above steps were helpful.
