(50 points) WILL GIVE BRAINEST TO CORRECT ANSWER Solve the system of equations.
x + 4y = 0
20y = - 5x

Substitute.
20y = -5(__)

System of Linear Equations entered :

 [1]           x+4y=0

 [2]           20y=-5x

Equations Simplified or Rearranged :

  [1]    x + 4y = 0

  [2]    5x + 20y = 0

Solve by Substitution :

// Solve equation [1] for the variable  x

 [1]    x = -4y

// Plug this in for variable  x  in equation [2]

  [2]    5•(-4y) + 20y = 0

Sure hope this helps you and pls mark me brainiest :D

Multiply 5 with equation (1)

Compare equation(2) and (3)

Both are equal hence no solution
