Answer:

x=4 and y=−4

Step-by-step explanation:

Let's solve your system by elimination.

−x−2y=4;3x+2y=4

−x−2y=4

3x+2y=4

Add these equations to eliminate y:

2x=8

Then solve 2x=8 for x:

2x=8

2x

2

=

8

2

(Divide both sides by 2)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

−x−2y=4

Substitute 4 for x in−x−2y=4:

−4−2y=4

−2y−4=4(Simplify both sides of the equation)

−2y−4+4=4+4(Add 4 to both sides)

−2y=8

−2y

−2

=

8

−2

(Divide both sides by -2)

y=−4
