Question
  • As part of a solution for finding the forces acting on a body in an equilibrium condition, you got to the following system of equations to solve and find the forces X1 , X2 , X3

 X1 – 2X2 + X3 = 3

2X1 + X2 − X3 = 5

3X1 − X2 + 2X3 = 12

Use Inverse Matrix Method to solve for the unknown forces.
