Question

solve for x and y by solving these equations above. answer must be in x,y form

please help​

Answer 1

Hi there! :)

$\large\boxed{(-2, -2)}$

y = 2x + 2

y = -2x - 6

Both equations are equal to "y", so we can simply set both equations equal to each other:

2x + 2 = -2x - 6

Add "2x" to both sides:

2x + 2x + 2 = -6

Subtract "2" from both sides:

4x = -8

Divide both sides by 4:

4x/4 = -8/4

x = -2

Substitute in this value of "x" back into either of the equations:

y = -2(-2) - 6

y = 4 - 6

y = -2

Therefore, the solution of the equations is at (-2, -2).

Answer 2

Answer: (-2,-2)

Step-by-step explanation:

y = 2x + 2  

y = -2x -6  

Solve using the substitution method. Set the equations equal to each other and solve for x.

2x + 2 = -2x -6      Add 6 to both sides

    +6           +6

2x + 8  = -2x    subtract 2x from both sides

-2x          -2x

  8= -4x     Divide both sides by -4

x = -2  

Since the value for x is -2 input it into one of the equations and solve for  y.

y = 2(-2) + 2

y = -4 + 2

y = -2  

The solution is  (-2,-2)
