Mathematics

Answer:

Step-by-step explanation:

To graph by hand I would first convert both equations into y=mx+b.

We start with:

\left \{ {{2x-2y=4} \atop {x+2y=8}} \right.

Solve for y for 2x-2y=4

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

Solve for y for x+2y=8

x+2y=8\\2y=8-x\\y=4-\frac{x}{2}

Giving the new but equal system of equations:

\left \{ {{y=2x-x} \atop {y=4-\frac{x}{2} }} \right.

From this point on you can graph the two functions to find where the two lines intersect, thats your solution.

I've gone ahead and graphed it on desmos for you
