Taking 11 common from LHS seperating z and breaking 151001 as a factor of 11 with some remainder in RHS

11(113v+112w+11x+y) + z = 11x13727 + 4 [hence; z = 4]

Equating z =4 and cancelling 11 from each side we get the following simplified equation and again repeating the above procedure;

11(112v + 11w +x) + y =11x1247 + 10 [y = 10]

11(11v + w ) + x = 11x113 + 4 [x = 4]

11v + w = 11x10 + 3 [v=10 , w=3]

So we get the unique solution for the above equaton.

b,11(y+11x+121w+1331v)+z=11*13727+4,z=4
11(x+11w+121v)+y=11*1247+10,y=10
11(w+11v)+x=11*113+4,x=4
11v+w=11*10+3,v=10,w=3
so it gives the unique sol
