A single equation representing both lines x+y=0 and x+2y = 0 is ? August 2, 2021 by Cherry A single equation representing both lines x+y=0 and x+2y = 0 is ?

Answer: The single equation is [tex]y = 0[/tex] Step-by-step explanation: We are given the following system of equations: [tex]x + y = 0[/tex] [tex]x + 2y = 0[/tex] From the first equation: [tex]x = -y[/tex] Replacing in the second equation: [tex]-y + 2y = 0[/tex] [tex]y = 0[/tex] The single equation is [tex]y = 0[/tex] Reply

Answer:The single equation is [tex]y = 0[/tex]

Step-by-step explanation:We are given the following system of equations:[tex]x + y = 0[/tex]

[tex]x + 2y = 0[/tex]

From the first equation:

[tex]x = -y[/tex]

Replacing in the second equation:

[tex]-y + 2y = 0[/tex]

[tex]y = 0[/tex]

The single equation is [tex]y = 0[/tex]
