Question

Solve the system of equations using Substitution


8x + 4y = 12
y = -2x + 3

Answer 1

Answer:

Step-by-step explanation:

System of Linear Equations entered :

 [1]           8x+4y=12

 [2]           y=-2x+3

Equations Simplified or Rearranged :

  [1]    8x + 4y = 12

  [2]    2x + y = 3

Solve by Substitution :

Solve equation [2] for the variable  y  

 [2]    y = -2x + 3

Plug this in for variable  y  in equation [1]

  [1]    8x + 4•(-2x+3) = 12

  [1]    0 = 0 =>  Infinitely many solutions
