For this case we have the following equation: (3/4) z - (1/4) z + 3 = (2/4) z + 5 Rewriting we have: z (3/4 - 1/4) + 3 = (2/4) z + 5 z ((3-1) / 4) + 3 = (2/4) z + 5 z (2/4) + 3 = (2/4) z + 5 (2/4) z + 3 = (2/4) z + 5 (2/4) z - (2/4) z + 3 = 5 3 = 5 Equality is not met. Answer: a. It has no solution.
