Y=4Y+30

I did;

Y-4Y=-3Y

My equation

-3Y=30--->30/-3

I get -10

yet the checking does not work.

Does the negative go on the whole 3Y or just the 3?

**Jai**, Sunday, October 27, 2013 at 4:22pmYour solution and answer are actually correct. :)

Let's do the checking part:

Y = 4Y + 30

if Y = -10,

-10 = -10(4) + 30

-10 = -40 + 30

-10 = -10

Since both sides of the equation are equal, then Y is indeed equal to -10.

Hope this helps :3

**Nicole**, Sunday, October 27, 2013 at 4:29pmI don't have to make it positive?

**Jai**, Sunday, October 27, 2013 at 5:12pmNo, you don't have to.

30 / 3 = 10

Here, 10 is positive because both 30 and 3 are positive.

30 / -3 = -10

While here, one of them is negative so the answer must also be negative.

*Note that if however, both 30 and 3 are negative, the answer is positive.
