xx*x=xx+xx=xxReplace all x by nos. from 1-9. You must not repeat any nos. and fulfill the given conditions. One x can be replaced by only one no. from 1-9. If you manage to solve it please tell me what is the logic behind this. In case somethings are not clear then:* means multiplication.+ means addition.Please help urgently!!You have to fulfill all the conditions mentioned.Yes you have to use only one no. from each 1-9 to fill the x marks.

I have written a small C++ code to find answers of this equation, and the result is: "This equation has no answers."!
