Answer: X and Y = 300 + 200
Step-by-step explanation: Find two numbers that add up to 500 and make sure that you can subtract them and get 100.
Answer:
X=300, Y=200
Explanation:
If: X+Y=500,
Then Y = 500-X
IF X-Y=100,
Then:
X-(500-X)=100,
X-500+X=100,
2X-500=100,
2X=100+500
2X=600
X=300.
So,
X+Y=500,
300+Y=500
Y=500-300
Y=200
