Hello there!

Reminder: Your question will be removed if you have more than 3 questions in the post.

1:

3 ( -3 + 7x ) ≤ - 93

-9  + 21x ≤ 93

93 + 9 = 102

102/21 = 4.857

4.857 --> 4.86

4.86  ≤  x

2:

-6 ( 1 + 8x ) ≥ 138

-6 - 48x ≥ 138

138 + 6 = 144

144/-48 = -3

x ≥ -3

3:

7 ( 6x -4 ) ≥ 6x - 28

42x - 28 ≥ 6x - 28

36x - 28 ≥ -28

-28 + 28 = 0

36x ≥ 0

4:

86 ≤ -4 ( 1-5x) -2x

86 ≤ -4 + 20x - 2x

86 ≤ -4 + 18x

90 ≤ 18x

90/18 = 5

x ≤ 5
