Suppose a, b, c, and d are integers and a ?= c. Suppose also that x is a real number that satisfies the equation ax + b cx + d = 1. Must x be rational? If so, express x as a ratio of two integers.

1. 2y = 4 -x = -3 what is the solution to this system of equations? a) (2, 3) b) (-3, 2) c) (3, 2) d) (-3, 4) 2. 2x - y = 5 3x + 2y = 4 solve the system of equations. a) (3, 1) b) (0, 2) c) (2, -1) d) (9/7, 17/7)
