Answer:
x=4 and y=1
Step-by-step explanation:
Step: Solvex+y=5for x:
x+y=5
x+y+−y=5+−y(Add -y to both sides)
x=−y+5
Step: Substitute−y+5forxinx−y=3:
x−y=3
−y+5−y=3
−2y+5=3(Simplify both sides of the equation)
−2y+5+−5=3+−5(Add -5 to both sides)
(Divide both sides by -2)
−2y=−2
/−2y
−2
=
−2
/−2
y=1
Step: Substitute1foryinx=−y+5:
x=−y+5
x=−1+5
x=4(Simplify both sides of the equation)
Answer:
x=4 and y=1
