Question

3. Solve the following equations:
(a) 4 = 5(p-2) (b) - 4 = 5(p-2)​

Answer 1

Answer:

$(a) \: 4 = 5(p - 2) \\ \\ or \: 5(p - 2) = 4 \\ \\ = > 5p - 10 = 4 \\ \\ = > 5p = 4 + 10 \\ \\ = > 5p = 14 \\ \\ = > p = \frac{14}{5}$

$(b) \: - 4 = 5(p - 2) \\ \\ or \: 5(p - 2) = - 4 \\ \\ = > 5p - 10 = - 4 \\ \\ = > 5p = - 4 + 10 \\ \\ = > 5p = 6 \\ \\ = > p = \frac{6}{5}$
