Answer:
(4,8)
x=4
y=8
Step-by-step explanation:
x is the first number
y is the second number
x+y=12
x-y= -4
Let's add y and 4 to the second equation to get y by itself
x+4=y
We can substitute this value in for y in the first equation
x+x+4=12
2x=8
x=4
We can then use x=4 and plug that into any equation
4+y=12
y=8
The answer is (4,8)
