Question

What is x+8y=-15 7x+8y=-19

Answer 1

x = − 15 − 8 y

y=-7/8x-19/8

Explanation:

If you are trying to solve for x the answer for first problems is

x = − 15 − 8 y

second problem the slope intercept form is:

y=-7/8x-19/8

I'm not sure exactly what you are looking for but I hope that is it.

Answer 2

you would subtract the x and move it over to the other side so your equation would be
8y= -15 + x
you would then divide everything by 8 so you can have y on its own so it would be
y= -15/8 + x/8
so your final equation is
y=-15/8 +8x

for the second equation it’s the same thing, you subtract 7x
8y= -19 + 7x
divide by 8
y= -19/8 +7/8x
