2 answers:
Answer: x=31 and y = 19
Step-by-step explanation:
X+y=50
X-y=12
2x + 0y = 62
Divide both sides by 2
2x/2 = 62/2
x = 31
Now find y by plugging in 31 for x
31+y = 50
Subtract 31
y = 50-31
y = 19
Answer:
The two numbers are 31 and 19
Step-by-step explanation:
Let x and y be the numbers
x+y = 50
x-y = 12
Add the two equations together
x+y = 50
x-y = 12
-----------------
2x +0y = 62
Divide by 2
2x/2 = 62/2
x = 31
Now find y
31+y = 50
Subtract 31
y = 50-31
y = 19
