In general, you can do all of them this way.
1. Eliminate parentheses using the distributive property.
2. Collect terms.
3. Identify the variable term with the smallest (most negative) coefficient.
4. Add the opposite of everything on that side of the inequality and simplify.
5. Divide by the coefficient of the variable.
6. Add the opposite of the constant.

Using problem #5 as an example:
  7x -3(4x -8) ≤ 6x +12 -9x
  7x -12x +24 ≤ 6x +12 -9x . . . . . eliminate parentheses
  -5x +24 ≤ -3x +12 . . . . . . . . . . . collect terms. Left side has smallest x term.
  0 ≤ 5x -3x -24 +12 . . . . . . . . . . add opposite of left side
  0 ≤ 2x -12 . . . . . . . . . . . . . . . . . collect terms
  0 ≤ x -6 . . . . . . . . . . . . . . . . . . . divide by x-coefficient, 2
  6 ≤ x . . . . . . . . . . . . . . . . . . . . . add the opposite of -6
