7. By using a free body analysis, an idealized three springs-mass system gives the following system of equations:
Applying the Gauss-Seidel method obtain two iterations to get the displacements of the masses at rest x1,x2 and x3. Gross approximations that can be used as initial values are x1^0= 5, x2^0 =10 and x3^0 = 10
