Answer:
10
Step-by-step explanation:
10+4 is 14 amd 14-4 is 10
Answer:
Numbers are 9 and 5
Step-by-step explanation:
x + y = 14
x - y = 4
Rewrite 1st equation
x = 14 - y
Put this into the other
14 - y - y = 4
14 - 2y = 4
14 = 4 + 2y
10 = 2y
y = 5
x + y = 14
x + 5 = 14
x = 9
Check answers both equations!!
9 + 5 = 14 Correct
9 - 5 = 4 Correct
