    Let x represent the envelope and y also represent the stamp

    So, x+y=$2.50

    For the envelope i.e x to cost 2 more than the stamp i.e y

    We have x=y+2

    By forming a simultaneous equation

    x+y=2.50...eqn 1

    x=y+2...eqn 2

    Put x into eqn 1

    So we now have

    (y+2)+y=2.50

    y+2+y=2.50

    2+2y=2.50

    2y=2.50-2

    2y=0.50

    Divide both sides by 2

    y=0.25

    Therefore, y which represent stamp is $0.25

     The envelope is now 4.50  minus the stamp amount which is 2.50 .... So therefore 4.50-2.50=2.00 ...the stamp is 2.00
