∙ 13y agoYou 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.

How do you solve 2x-y equals -6 and 2x plus 3y equals 9?
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
2x - 5 plus 5 equals 12 solve for x?
X=6
How do you solve 12 equals 2x plus 6?
12 = 2x + 6 subtract 6 from both sides 6 = 2x divide both sides by 2 3 = x
2x plus 3y equals 6 solve for x?
this can not be solved un less with another equation
Can You Solve 2x plus 3y equals 18 and 2x-3y equals -6 Using The Elimination Method?
Yes and it works out that x = 3 and y = 4
How do you solve 22 plus 2x equals 37 plus 6 plus x?
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
Solve 2x plus 8 equals 6?
2x+8 = 6 2x = 6-8 2x = -2 x = -1
How do you solve 2x-y equals -6 and 2x plus 3y equals 9?
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
How do you solve 2x plus 7 equals 1?
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
2x - 5 plus 5 equals 12 solve for x?
X=6
How do you solve 12 equals 2x plus 6?
12 = 2x + 6 subtract 6 from both sides 6 = 2x divide both sides by 2 3 = x
How do you solve 6x plus 6 equals 2x-4?
4x=-10 x=-2.5
Are the graphs of 2x plus 7y equals 6 and 7y equals 2x plus 6 parallel?
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.
What is 2x-6 equals x plus 5?
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.
2x plus 3y equals 6 solve for x?
this can not be solved un less with another equation
Can You Solve 2x plus 3y equals 18 and 2x-3y equals -6 Using The Elimination Method?
Yes and it works out that x = 3 and y = 4
Solve-3x-2 equals 2x plus 4 for x?
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
