Question
  1. Solve the system of equations with elimination method and what is the type of solution? x + y= -1;      2x =8 +3y;    x+2y= -3;   4x-3y =10
  2. Determine whether there is a combination of three components satisfying the system. Apply Gaussian elimination procedure.

X1 + X2 + X3 = 200,000

0.1X1+0.07X2+0.08X3=16,000

X2 + X3 =3 X1
