    Step-by-step explanation:

    Equations derived from given info.

    P=2J J=E+40 P+J+E=300

    Use some substitution now.

    P=2 (E+40) J=E+40 P+J+E=300

    Substitute first and second equation into third.

    2 (E+40) + E+40+E=300 2E+80+E+40+E=300 4E+120=300 4E=180 E=45

    Emily has 45 stickers. But we want to know what Peter has.

    Use P=2 (E+40)

    P=2 (45+40) P=90+80 P=170

    Peter has 170 stickers.
