Question

x-5y=10, 3x-15y=-15 por metodo de reducción

Answer 1

System of Linear Equations entered :

  [1]    x - 5y = 10

  [2]    3x - 15y = 15

Solve by Substitution :

// Solve equation [1] for the variable  x  

 

 [1]    x = 5y + 10

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

  [2]    3•(5y+10) - 15y = 15

  [2]    0 = -15 =>  NO solution
