Answer:
the two numbers are 30 and 18
Step-by-step explanation:
Let the two numbers be m and n then
m+n=48.............i)
m - n = 12 ...............ii)
Adding both equations
2m = 60
m = 30
Putting m = 30 in equation i
30 + n = 48
n = 48 - 30
n = 18
18
30 + 18 = 48
30 - 18 = 12
Both true, so our solution is correct.
