2x - 7y+15=0
7y = 2x +15
y= 2x/7 +15/7
This is the equation of a straight line with slope = 2/7,
y-intercept = (0,15/7), and
x-intercept = (-7,5,0)

X= -4
Y= 1

x = 7y/2 - 15/2
y = -2x/-7 - 15/7

you can't solve that because you don't know what x and y are. Did you get a key? Example x=20 or something that tells what x and y are? If you did all you have to do is plug in those numbers for the variables.

You have not asked a proper mathematical question. But you have expressed an "equation."
I assume you want to solve for x and y.
There are infinite definitions for each. I can tell this intuitively. Insert and test different numbers and you will see that there are more than one. So, there are infinitely many.

what are you solving for? X? or Y? if you are solving for X, the answer is X= -1.07 + Y
If you are solving for Y, the answer is Y= 1.07 + X (or instead of the 1.07 you can just use 7.5/7, but i went ahead and did the calculation, really its up to personal preference, they are the same number)

y=(-2x-15)/-7=((-1)(2x+15)/7

What about it? What do you want to solve for?

it can not be solved because there are two unknown variables.
