Answer:
x=−5 and y=−7
Step-by-step explanation:
Step: Solve y=2x+3for y:
y=2x+3
Step: Substitute2x+3foryin4x−3y=1:
4x−3y=1
4x−3(2x+3)=1
−2x−9=1(Simplify both sides of the equation)
−2x−9+9=1+9(Add 9 to both sides)
−2x=10
−2x
−2
=
10
−2
(Divide both sides by -2)
x=−5
Step: Substitute−5forxiny=2x+3:
y=2x+3
y=(2)(−5)+3
y=−7(Simplify both sides of the equation)
