3x+3 = 0
3x = -3
x= -1
6y+1 = 0
6y= -1
y = -1/6
7(-1)/ 3(-1/6)
the value of 7x/3y is 14
Given(3x+3)/(6y+1)=3,find the value of7x/3y.

from the given equation,
18y + 3 = 3x+3
18y = 3x
x = 6y
then 7x/3y
= 42y/(3y)
= 42/3
= 14
=
18y + 3 = 3x+3
18y = 3x
x = 6y
then 7x/3y
= 42y/(3y)
= 42/3
= 14
=
why3x+3=0 ??
okay i got it!thanks!!
good question, Olivia, since if 3x+3 = 0 we would have
0/(6y+1) = 3
0 = 3 which would be nonsense.
Jonel was just "lucky" to get the correct answer, since
x = -1 works in the simplified equation x = 6y
but not in the original equation.
0/(6y+1) = 3
0 = 3 which would be nonsense.
