plz find me the solution

[prithibi]

x, y and z are three integers and
xy+xy=yzz
find x+y+z

[rezbipul]

Here is your solution:

y must be one because y is the carry from the addition of the digits at tens position. That means z = 2.

Now the result of the addition is 122.

We get this equation:

2 * (10x+1) = 122; [xy means 10*x+1]
=> x = 3

So x+y+z = 3+1+2 = 6

I guess there's a tiny mistake in the solution above. Shouldn't x be 6?

[rezbipul]

Yeah you are right.

xy
+xy
_____
yzz

So, y is the carry of (x+x). We know that carry of addition is always 1. That means y=1. and y+y=z=2, x+x=yz=12 =>x=6

Thank you...

[prithibi]

thank all of u

[arif_khan]

xy + xy = yzz
its hard to get whether its
x*y format or
x*10+y format

[grexam]

yea exactly how can we make out in which format is the given question?
