    An equation is a statement that two expressions are equal, so we have:

    #"expression = expression"#

    An equation is solved, which means to find the value(s) of the variable(s) which makes the equation true,

    #3x-5 = 22" "rarr x = 9#

    #x^2 +4x -45 =0" "x = -9 or x=5#

    An equation which contains two or more variables does not have a unique solution, but rather many, many solutions,

    #x+y=10 # has infinitely many solutions.
