<span>(x - y + 1) - (x + y - 1)
x - y + 1 - x - y + 1
= (x - x) + (y - y) + (1 + 1)
= -2y + 2
In short, Your Answer would be: -2y + 2
Hope this helps!</span>

Answer:
3( 73/84 )left over
Step-by-step explanation:
She had 6 gallons in total 
2/3+1/4+1/2+5/7=179/84   =  2 ( 11/84)
6/1-179/84 = 325/84    =  3(73/84)
She used  179/84
She have left 325/84
179/84   +  325/84 = 6
    With mixed numbers:
2  11/84   
3  73/84
  2+3=5                11/84+73/84= 84/84 =1
5+1=6
