Question 207320
An  equation  has  an  =  sign,,,f(x) = "x+2"
.
so  our  problem  is  not  an  equation.
.
FYI,  a linear  equation,  has  x raised  to  only  the  first  power
.
A NON  linear  equation  has  x  raised  to  a  power  greater  than  1
.
.
Therefore,,5x-11,,is  an  expression,,,which  is  any  symbol.
