If y=2x
7y=14x .
6x+14x=20
20x=20
x being 1 x=1
we found x .
and putting in this problem.
y=2x
y will be 2 , y=2
i am so sorry for my bad english :(
So ten tens = 100 so u multiply and u get 40 tens which are 400= 4 hundreds
X=weight of the jug
y=witht of liquid when the jug is full
we suggest this system of equations:
x+y/5=250
x+4y/5=550
we solve this system of equations by equalization method.
x=250-y/5
x=550-4y/5
250-y/5=550-4y/5
least common multiple=5
1250-y=2750-4y
-y+4y=2750-1250
3y=1500
y=1500/3
y=500
x=250-y/5
x=250-500/5
x=250-100
x=150
Answer: weight of the jug = 150grams.
