Answer:
x=5, y= -1
Step-by-step explanation:
Let's solve your system by substitution.
x+2y=3;x−y=6
Step: Solvex+2y=3for x:
x+2y=3
x+2y+−2y=3+−2y(Add -2y to both sides)
x=−2y+3
Step: Substitute−2y+3forxinx−y=6:
x−y=6
−2y+3−y=6
−3y+3=6(Simplify both sides of the equation)
−3y+3+−3=6+−3(Add -3 to both sides)
−3y=3
−3y
−3
=
3
−3
(Divide both sides by -3)
y=−1
Step: Substitute−1foryinx=−2y+3:
x=−2y+3
x=(−2)(−1)+3
x=5(Simplify both sides of the equation)
Answer:
x=5 and y=−1
I really hope this helped pls mark brainliest if you dont mind. thx :)
