Answer:

(-6, -8)

Explanation:

We have the following system of equations:

y = 2x+4 (1)

and


y=x-2 (2)

Set (1) = (2) since the LHS is y in both

We get


2x + 4 = x - 2

Subtract x from both sides:


2x + 4 - x = x - 2 -x


x + 4 = -2

Subtract 4 from both sides


x + 4 - 4 = -2 -4


x = -6

Substitute for x in Equation (2) to get

y = -6 - 2 = -8

So the solution is (-6, -8)
