Solve: x - 1 < 3
explain if possible.

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Which coefficient matrix represents a system of linear equations that has a unique solution ? options in photo*

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
