Math help please!!!! 10 POINTS!!!

Solve this system of equation by graphing. I am aware that you are unable to graph it for me, but was wondering how to solve the equation to get the points to plot the graph. Thanks in advance!!!

2x - 2y = -4
x + y = 6

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

x + y = 6
y = -x + 6

Set them equal to each other.

x + 2 = -x + 6
2x = 4
x = 2

Plug x into the equation.

y = -x + 6
y = -(2) + 6
y = -2 + 6
y = 4

The coordinates where they meet are (2,4).

you can make a graph of each line with only two points per line so I'm going to give you the points so you can pass them to a cartesian axis and meke the lines then you will find that they croy in the point (2,4) that it's the solution for the system

the point are (0,2) and (6,8) for the first one
and (0,6) and (6,0) for the second one

For the first one:
2x - 2y = -4
-2y = -2x - 4 (subtract 2x from both sides)
y = x + 2 (divide both sides by -2)

Second one:
x + y = 6
y = -x + 6 (subtract x from both sides)
