A full jar of honey weighs 750 grams, and the same jar two-thirds

full weighs 550 grams. What is the weight of the empty jar in grams

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
