Answer:

5 & 8

Step-by-step explanation:

x-y = 3 -> x = 3+y

x+y = 13 = 3+y+y -> 3+2*y = 13

2*y = 10 -> y = 5

-> x = 3+y = 8

I’m not very good at math but here’s my reasoning:
x/2-7=9
I moved the 7 to the other side of the equation
So now
X/2 = 9 + 7
X/2 = 16
Since x is equal 16 if you divide x by 2 (because x/2=16), that means if you want to find x you need to multiply x by 2
X = 16 x 2
X = 32
I hope it’s right !! <3
