Question

X+2y=13 solve for y.

Answer 1

Answer:

y=-1/2x+6.5

Step-by-step explanation:

x+2y=13

We want to put this in Y=Mx+b form so we need to get Y alone.  To do this we must subtract x from both sides

2y=-x+13

Now we must get rid of the 2 so to do that we have to divide 2 to the -x and 13 along with the 2

You then get your final answer of y=-1/2x+6.5

Answer 2

Step-by-step explanation:

So we have the given equation x + 2y = 13

To solve for y, we must first isolate y, so:

x + 2y = 13

2y = 13 - x

$y=\frac{-x + 13}{2}$

Or in point-intercept form:

$y=\frac{-1}{2}x+ \frac{13}{2}$
