Generally, x <span>• x is accepted to mean "x times x" or "x multiplied by x"
and x+x means "x plus x" or "x added to x"
let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x</span><span>•x" is false, then it is not true
let's try x=4
x+x=x</span><span>•x
4+4=4</span>•<span>4
8=16
false
so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x</span><span>•x, we would get that it is only true for x=2 and x=0)
it is not always true
