Let the first number be x and decide number be y
therefore x+y = -42
also. x-y = 52 using the process of elimination
we get: 2x = 10
we divide both sides by 2, which gives us x=5
then we substitute the value of x in the first equation
that gives us. 5+y = -42
thus. y = -47
A 5 or a queen
52 cards per deck
each card repeats 4 times
a 5 or a queen
there are four 5's and four queens
4+4=8
probablity=desiredoutcomes/totalpossible
probablity=8/52
probablity=4/26
probablity=2/13

Hello!
The solution is where the lines intersect. As you can see, they only intersect at one point.
A) It as one solution.
To find our solution, we just see what the point is they intersect at.As you can see, they intersect at (4,4).
B) (4,4)
I hope this helps!
