Please help with my math problem. An explanation would be much appreciated!

Take any two ordinary constants. (e.g. x and y)
Make them alike, as in x = y = any non-zero number (in this case, 2)
Multiply each by y, but x works equally well (y²=xy).
Subtract x² from each equation (y²-x² = xy-x²).
Factor y²-x² into (y+x)(y-x) to make ((y-x)(y+x) = xy-x²).
Factor xy-x² into x(y-x) to make ((y-x)(y+x) = x(y-x)).
Divide by (y-x) to get (y+x=x).
Subtract x from both sides of this equation to get y=0.
This means that y=0.
but since, y equaled 2 in the first case, that means 2 = 0.
If you multiply this equation by 2.5, you get 5 = 0.
Since 0 + 0 = 0, you can plug in 2 for the first two zeroes, and five for the last one, and then, 2 + 2 = 5.
So the answer is 5 :p

not 1, 2, 3, 5, 6, 7, 8, or 9. So probably 4

2 + 2 = 10 for large values of 2.
