Answer:
25)
v - 6(4v + 6) = - 82
v - 24v - 36 = - 82
v - 24v = - 82 + 36
- 23v = - 46
- v = - 46/23
- v = - 2
<h2>v = 2</h2>
26)
- 96 = 4(6n - 6)
- 96 = 24n - 24
- 96 + 24 = 24n
- 72 = 24n
- 72/24 = n
- 3 = n
<h2>n = - 3</h2>
27)
- 2(- 5a - 2) = 84
10a + 4 = 84
10a = 84 - 4
10a = 80
a = 80/10
<h2>a = 8</h2>
28)
7(7 + 3k) = 217
49 + 21k = 217
21k = 217 - 49
21k = 168
k = 168/21
<h2>k = 8</h2>
