rref( ) row echelon form MATLAB

I found the row echelon form of my matrix A but now I am trying to find the solution set to the system. Is there a function that can do that in a way that rref( ) found the row echelon form? This is what I have so far:
A = [-1, 2, -3; 4, -5, 6]
R = rref(A)
I know once I have my row echelon, I want to get u1 = -1 and u2 = -2 but I do not know what the function is in matlab that performs this calculation.
Any guidance would be great

A=[-1 2;4 -5];

@David Hill what does the line
x = A\b
do? I thought a solution set was solving across the matrix made using rref(A)
