This cannot be the question. You definitely read this wrong. If p(notA)= .75 then P(not A) = .75...
If the question is find P(A), however, then the use the compliment rule
1- P(not A) = P(A)
1-.75 = .25
There are 3 answers for this which are (10,2), (8,1), and (14,-1).
Hey there!
The answer is 
To solve this we use subtraction, because "the difference" represents subtraction, so:
Now, we must find a common denominator, and we can see that 
and 
both go into 
. To get to , we multiplied the first fraction by 5 and the second by 6, so we now have:
This is equal to
Hope it helps and have a great day!

Answer:
21x + 29y - 8
Step-by-step explanation:
(−7x+8x+19y)−(6y+8−20x−16y)
−7x+8x+19y−6y-8+20x+16y
(−7x+8x+20x)+(19y−6y+16y)-8
21x + 29y - 8
