The value of x and y in the given equation  is determined -1 and -2 respectively.

<h3>Value of x and y</h3>

The value of x and y can be determined by solving the two equations simultaneously.

y = -2x - 4  ----- (1)

y = 4x + 2   ----- (2)

solve (1) and (2) together

-2x - 4 = 4x + 2

x = -1

y = 4(-1) + 2

y = -4 + 2

y = -2
