I'm actually in the process of learning algebra.

I know how to solve a lot of these problems.....explaining my work is the hard part.  I get used to all these problems that I do them naturally without thinking too hard,  then I don't realize how I did it.

Well 24+24=48  So that is how I'll start.  There is no difference between these.

25+23=48, but the difference is only 2

26+22=48, but the difference is only 4

27+21=48,  and the difference is 8

So, the numbers are 27 and 21

Let x be the first number and y be the second number....so we have

x + y = 48

x - y  =   6 

add the equations

2x = 54           

divide by 2 on both sides

x = 27

And  27 - y = 6  →  y = [ 27 - 6 ] = 21

So x = 27 and y = 21

Happy7, have you taken Algebra yet???

If not, when you take it, you will see how to solve many of these problems without having to "guess and check.'  I actually admire your ability to use logical reasonng to figure out some of these answers !!!
