Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

10x+3y=5;x=y-4  

Solution :

{x,y} = {1,5}  

 

System of Linear Equations entered :

  [1]    -10x + 3y = 5

  [2]    x - y = -4

Graphic Representation of the Equations :

   3y - 10x = 5        y + x = -4  

 

 

Solve by Substitution :

// Solve equation [2] for the variable  x  

 

 [2]    x = y - 4

// Plug this in for variable  x  in equation [1]

  [1]    -10•(y -4) + 3y = 5

  [1]     - 7y = -35

// Solve equation [1] for the variable  y  

  [1]    7y = 35  

  [1]    y = 5  

// By now we know this much :

   x = y-4

   y = 5

// Use the  y  value to solve for  x  

   x = (5)-4 = 1  

Solution :

{x,y} = {1,5}
