Answer 1

A-3X-5(2-X)-3(1-X)
   3x-10+5x-3+3x
   3x+3x+5x-10-3
   11x-13

B-3+2Y-5+X+5Y+10
   x+2y+5y+10+3-5
   x+7y+8

C-2X+3Y-1+5X-2Y-7
    2x+5x+3y-2y-7-1
    7x+y-8

D-7AX+AY-8AX+3AY
   7ax-8ax+3ay+ay
   -ax+4ay

Answer 2

A-3X-5(2-X)-3(1-X) ==> 3x - 10 + 5x - 3 + 3x ==> 2x+3x+5x -10-3==> 10x - 13

B-3+2Y-5+X+5Y+10==> x + 2y + 5y + 3 + 10==> x + 7y  + 13

C-2X+3Y-1+5X-2Y-7==>2x + 5x + 3y - 2y - 1 - 7 ==> 7x - y - 8

D-7AX+AY-8AX+3AY ==> 7ax - 8ax +ay + 3ay ==> - ax + 4ay
