    150 grams

    Step-by-step explanation:

    The weight of the full jar of honey is equivalent to x + y, where x is equal to the weight of honey and y is equal to the weight of the jar.

    x+y = 750

    2x/3+y = 550

    You can solve for y in the first equation and get:

    y = 750-x

    Plug that in to the second equation and you get:

    -x/3+750 = 550

    Subtract 750 from both sides:

    -x/3 = - 200

    Multiple - 3 on both sides:

    x = 600 grams

    The weight of the jar is 750-600 or 150
