Answer:
28 and 52
Explanation:
Call the unknown numbers x and y.
X + Y = 80
Y - X = 24
We can use substitution to solve for the numbers.
Y = 24-x (see how i just rearranged the 2nd equation?)
Use that ^^^ back in the first equation.
X + Y = 80
X + (24-x) = 80
2X + 24 = 80
2X = 80-24
2X = 56
X = 28
So we know that X = 28. Solve for Y.
X + Y = 80
28 + Y = 80
Y = 80-28
Y = 52
Double check! Do the numbers equal 80?
28 + 52 = 80
Is the difference btwn the numbers 24>
52 - 28 = 24
