Answer:

x= -1/2 and y=-5/2

Step-by-step explanation:

Step 1: Solve x−y=2 for x:

x−y=2

x−y+y=2+y(Add y to both sides)

x=y+2

Step 2: Substitute y+2 for x in x+y=−3:

x+y=−3

y+2+y=−3

2y+2=−3(Simplify both sides of the equation)

2y+2+−2=−3+−2(Add -2 to both sides)

2y=−5

Divide both sides by 2.

y=-5/2

Step 3: Substitute -5/2 for y in x=y+2:

x=y+2

x=-5/2+2

x= -1/2 (Simplify both sides of the equation)

Answer: x= -1/2 and y=-5/2
