1) Let A be a square matrix with determinant equal to 0. Prove that if X is a solution to the equation Ax=b then every solution to this equation must have the form x=X+xot where xo is a solution of Ax=0.

2) Find a basis for the solution space of the following system of equations.
x- 2x2+ x3 =-4
-2x +3x2 + x4=6
3x -3x2 -3x3 -12x4=-6
-3x +5x2 -x3 +4x4=10

1) Let A be a square matrix with determinant equal to 0. Prove that if X is a solution to the equation Ax = b then every solution to this equation must have the form x = X + xo where xo is a solution of Ax = 0.
Since x0 is a solution to Ax = 0, we have Ax0 = 0 ......(i)
Since X is ...
