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
