The matrix given is in reduced echelon form.

	1	0	3		4
0	1	5		3
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.)

row 1	x1+3x3	= 4
row 2	x2+5x3	= 3
row 3	0x1+0x2+0x3	= 0

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.)

(x₁, x₂, x₃) =
