Answer:
n = 8
Step-by-step explanation:
7(2n + 6) = 154
7 * 2n + 7 * 6 = 154
14n + 42 = 154
(- 42) + 14n + 42 = 154 (- 42)
14n = 112
14n / 14 = 112 / 14
n = 8
Answer:
n = 8
Step-by-step explanation:
7(2n + 6) = 154
7 * 2n + 7 * 6 = 154
14n + 42 = 154
(- 42) + 14n + 42 = 154 (- 42)
14n = 112
14n / 14 = 112 / 14
n = 8
