Answer:
x = 1 and Y = -3
Step-by-step explanation:
Rewrite equations:
y=−3x;6x−9=y
Step: Solvey=−3xfor y:
y=−3x
Step: Substitute−3xforyin6x−9=y:
6x−9=y
6x−9=−3x
6x−9+3x=−3x+3x(Add 3x to both sides)
9x−9=0
9x−9+9=0+9(Add 9 to both sides)
9x=9
9x
9
=
9
9
(Divide both sides by 9)
x=1
Step: Substitute1forxiny=−3x:
y=−3x
y=(−3)(1)
y=−3(Simplify both sides of the equation)
Answer:
x=1 and y=−3
