Please help me solve these, thank you so much!

1.

Solve for (x,y,z)

2x + 5y + 3z = 16

x/5 + y/2 + z/3 = 2

3x - 2y - 4z = -2

State clearly whether this system is consistent or inconsistent. State whether the solution is unique, or if there are an infinite number of solutions, or no solution at all. If the solution is unique, state the solution.

2.

The equations of three planes are:

3x + 2y + 7z = 25 (1)

2x + y + 4z = 14 (2)

5x + 3y + 11z = 39 (3)

Solve the above system of equations. State whether this system is consistent or inconsistent and how many solutions there are.
