Answer 1

$(a) \: x = 1 \\ (b) \: x = 6\\ (c) \: z = 4\\ (d) \: x = 1 \\ (e) \: x = 6$

Step-by-step explanation:

$(a) \: 10x - 1 = 15 - 6x \\ 10x + 6x = 15 + 1 \\ 16x = 16 \\ x = 1 \\ (b) \: \frac{3x}{2} + 5 = \frac{5x}{2} - 1 \\ 5 + 1 = \frac{5x}{2} - \frac{3x}{2} \\ 6 = \frac{2x}{2} \\ 6 = x \\ x = 6 \\ (c) \: 1 \frac{1}{2} z - 2 = 3 \frac{1}{4} z - 9 \\ \frac{3z}{2} - 2 = \frac{13z}{4} - 9 \\ 9 - 2 = \frac{13z}{4} - \frac{3z}{2} \\ 7 = \frac{13z - 6z}{4} \\ 7 = \frac{7z}{4} \\ 1 = \frac{z}{4} \\ z = 4\\ (d) \: 9x - 8 = 11x - 10 \\ 10 - 8 = 11x - 9x \\ 2 = 2x \\ x = 1 \\ (e) \: \frac{x}{2} + \frac{x}{3} = 5 \\ \frac{3x + 2x}{6} = 5 \\ \frac{5x}{6} = 5 \\ \frac{x}{6} = 1 \\ x = 6$
