These are all just basic steps. You can't get far without them.

5 - 3(2x+4) = 25
Multiply each term in the parentheses by -3
5 + (-3)(2x) + (-3)(4) = 25
5 - 6x - 12 = 25

2) First distribute the -3
-3x +12 = 2x +10

3) 3 - x - 4 = 7

4) Distribute -2 to get rid of parentheses OR subtract 5 from both sides (It just depends on the style of the person).

5) Distribute to get rid of the parentheses.
5 -12x - 21 = 2x + 10

Question 1
5 - 6x - 12 = 25
- 7 - 6x = 25
- 32 = 6x
x = - 32 / 6
x = - 16 / 3

Question 2
-3x + 12 = 2x + 10
2 = 5x
x = 2 / 5

Question 3
3 - x - 4 = 7
- 1 - x = 7
- 8 = x
x = - 8

Question 4
5 - 8 + 2x = 17
- 3 + 2x = 17
2x = 20
x = 10

Question 5
5 - 12x - 21 = 2x + 10
- 16 - 12x = 2x + 10
- 26 = 24x
x = - 26 / 24
x = - 13 / 12
