Answer:
Explain the solution steps:
a) 5x - 34 = 162: 2
5x -34 = 81
5x = 81 + 34
5x = 115
x = 115: 5
x = 23
b) 14- | x-3 | = 8
x-3 = 14-8
x- 3 = 6
x = 6 + 3
x = 9
c) (72-x) + 6 ^ 15: 6 ^ 14 = 21
(72-x) +6 = 21
72-x = 21-6
72-x = 15
x = 72-15
x = 57
d) 3 ^ x + 1 + 3 ^ x + 2 = 324
3 ^ x .3 + 3 ^ x.3 ^ 2 = 324
3 ^ x + 3 ^ x. 9 = 324
3 ^ x + 12 = 324
3 ^ x = 324: 12
3 ^ x = 27
3 ^ x = 3 ^ 3 = 27
=> 3 ^ x = 3
wish you good study :))))
