The sum of two numbers is 24. The difference of the numbers is 16. Find the numbers.
This is what I have so far:
x+y-16=24

Nevermind about this question, I solved it myself.
first we solve this with variables x and y
x+y=24
x-y=16
now, you add the two equations
2x, the y cancelled
24+16 = 40
2x= 40
now you divide both sides by 2
x= 20
now, using the equation x +y=24
20 +y = 24
y= 24- 20=4
checking our answers
x+y=24
20+4=24
now, x-y=16
20-4=16
x+y=24
x-y=16
now, you add the two equations
2x, the y cancelled
24+16 = 40
2x= 40
now you divide both sides by 2
x= 20
now, using the equation x +y=24
20 +y = 24
y= 24- 20=4
checking our answers
x+y=24
20+4=24
now, x-y=16
20-4=16
Sum of two numbers is 100 and their difference is 50 the ratio between the two numbers is
