The matrix given is in reduced echelon form.

1	0	5	-2
0	1	2	5
0	0	0	0

Write the system of equations represented by the matrix. (Use x as your variable and label each x with its corresponding column. Enter x_1 for x₁, x_2 for x₂, and x_3 for x₃.)

Find the solution, if possible. (If there are infinitely many solutions, express x₁, x₂, and x₃ in terms of the parameter t. If there is no solution, enter NO SOLUTION.)
