Jam

A jar with jam weighs 800 grams. Jam weighs three times as much as the empty glass. What is the weight of the jam that is in the glass?

Correct answer:

x =  600 g

Step-by-step explanation:


x+y= 800
x=3y

x+y= 800
x=3·y

x+y = 800
x-3y = 0

Row 2 - Row 1 → Row 2
x+y = 800
-4y = -800


y = -800/-4 = 200
x = 800-y = 800-200 = 600

x = 600
y = 200
