This is algebra. Give the two unknown numbers names. For example, x and y
now use x and y in two different equations:
the sum of x and y is 110. Can you make that into an equation?
the difference of x and y is 28. Can you make that into an equation?
x+y = 110
x-y = 28
x = 69
y = 41
seems only one possible solution

Thank you so much(:!
Yes. Good job.
One easy way to solve is add the two equations together
x+y + (x-y) = 110+28
the y's cancel, and the x's add up to 2x, so you get
because x+y= 110 we know 69+y= 110
subtract 69 from both sides to get y= 41
Thank you!! This makes so much more sense to me now!
