I will give you 30points y = x + 4
5x + 3y = -4
Help please system by substitution

And help with y = 2x and
-8x – 2y = 24

Step-by-step explanation:

1) <---------- given linear equations

Equations Simplified or Rearranged :

Graphic Representation of the Equations : PICTURE #1

Solve by Substitution :

// Solve equation [1] for the variable  y

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

// Solve equation [2] for the variable  x

// By now we know this much :

// Use the  x  value to solve for  y

Solution :

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
