You have two equations. They are...

x=y+6 Equation (1)

y=-2-x Equation (2)

Since you know what "y" is you can solve by substitution. Substitute the second equation into the first.

x=(-2-x) + 6

x=4-x

2x=4

x=2

Now plug "x" into the second equation to find "y"

y=-2-2

y=-4

Now plug both "x" and "y" into both equations to see if I did them correctly

2=-4+6

2=2 Correct!

-4=-2-2

-4=-4 Correct!

So x=2 and y=-4 are the correct answers.

Q: How do you solve for x equals y plus 6 and y equals -2-x?

2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9

X=6

12 = 2x + 6 subtract 6 from both sides 6 = 2x divide both sides by 2 3 = x

this can not be solved un less with another equation

Yes and it works out that x = 3 and y = 4

Yes, they are. If you solve 2x + 7y = 6 for y, you get y = (-2x + 6) / 7. If you solve 7y + 2x + 6 = 0 for y, you get y = (-2x - 6) / 7. As you can see, both equations have the same slope. Therefore they are parallel. You can punch those equations into a graphing calculator and visually verify that they are indeed parallel.

To solve this equation we have to isolate and solve for x. So: 2x-6= x+5 +6 +6 2x = x+11 -x -x x = 11 So x=11.
