Question

The linear equation 4x+3y=10and 8x+6y=20

Answer 1

Answer:

there are infinitly many solution

Answer 2

Answer:

[1] 4x - 3y = 10   [2] 8x - 6y = 20

Solve by Substitution :

// Solve equation [2] for the variable  x 

 

[2] 8x = 6y + 20 [2] x = 3y/4 + 5/2

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

  [1] 4•(3y/4+5/2) - 3y = 10   [1] 0 = 0 => Infinitely many solutions
