There are a number of answers for this equation x=17 y=1, x=19 y=2
Bacially the answer is whatever y is x=2y+15

An equation in two variables has an infinte number of solutions. In this case all of those solutions fall on a straight line in the x,y-plane.
x-2y=15
-2y= 15 -x
y= (0.5)*x -7.5 is in the form y = mx + b
Therefore the line described by this equation has a slope of 0.5 and intersects the y-axis at -7.5.

x - 2y = 15
y= x/2 + 7.5
This is the equation of a line with slope = 1/2 and y-intercept =7.5

what are you trying to figure out
well if you are trying to get y alone
what u do is; /=divid
x-2y=15
-x -x
-2y=-x+15
divid by -2 on all sides
u get
y=0.5x-7.5

x-2y=15
-2y=15-x
2y= (15-x)/-1
2y = -15+x
y= -7,5+x/2
y = f(x) = -7,5+0,5x
So the function of x is increasing 0,5 times x
So when x increases with 1, y increases with 0,5.
And when x = 0, then y = -7,5 (this is the point where it goes through the y-axe.

if this is all the information, this answer is true for x=15 Y=0, X=17, y=1 etc. and y=-7.5, x=0, y=-8, x=1 etc.
