It is a linear equation because the highest power in the equation is 1. This is how you solve it: x+x=x x+x-x= x-x (you are doing the same thing to both sides of the equation so it stays the same) x=0 Thus the only solution to the equation is x=0.

Can the solution not be infinite?I mean x=infinite.

i dont think so... infinite isnt really a number so to speak, it is the idea of endlessness

@Shiva Jayabalan What do you think about? x+1=x? :)

@Siddharth Singh x+1-x=x-x, so 1 =0 This is false so the equation has no solution. Note that infinity is not a real number so it isnt a solution.
