X is 2

To find this, substitute the first equation of Y into the second equation, like this:

6x + 3 (3x - 5) = 15

Then, solve for x.

First, distribute the 3 into the parenthesis:

6x + 9x - 15 = 15

Then, combine like terms:

15x - 15 = 15

Add 15 to both sides to cancel out the -15

15x = 30

Now, divide by 15 on both sides to cancel out the 15 from the x.

x = 2x

Hope this helps!
