Having negative value for non basic variable gives a non feasible solution in simplex method?

Question

Objective function => x1 - 2x2
Subject to =>

x2 <= 5
x1 - x2 >= 2
x1 ,x2, x3 >= 0

Maximize?

convert to standard form :
Maximize -> -x1 + 2x2
Subject to ->

x2 <= 5
-x1 + x2 <= -2

convert to slack form :

Z = -x1 + 2x2
x3 = 5 - x2
x4 = -2 +x1 -x2

Basic solution (0,0,5,-2)

Can I found optimal solution in here? If not why?
