First: combine "like" terms - subtract 17 from both sides (when you move a term to the opposite side, always use the opposite sign).
4x + 17 -17 = 25-17
4x = 25 - 17
4x = 8
Sec: isolate "x" on one side by itself - divide both sides by 4.
4x/4 = 8/4
x = 8/4
x = 2

To solve 4x + 17 = 25, you need to get the variables on one side and the constants on the other side. So in this case:
4x + 17 = 25.
4x + 17 - 17 = 25 - 17. (Subtract 17 from both sides)
4x = 8.
x = 2.

4x + 17=25
4x + 17 -17 = 25 -17
This gets the 17 out of the way so you have
4x = 8
Then you divide (it is hard to write how it looks on here)
4x /4 = 8 /4
When you divide 4x by 4 you get x. Now the reason for this is that 4x is really 4 multiplied by x and you are doing the opposite by dividing, just like you did with subtracting 17, and that gets the four out of the way.
Now what ever you do to one side you have to do to the other side of the = sign. That's why we subtracted 17 and why we are dividing 8 by 4.
4x divided by 4 is x and 8 divided by 4 is 2
So you are left with
x=2

4x+17=25
-17=-17
4x=8
divide by 4 on both sides
x=2

subtract 17 from 25 then divide by that
4x+17=25
-17 -17
4x=8
4x/4=8/4
x=2

First combine the "non-x" terms:
4x + 17 - 17 = 25 - 17
4x = 8
Now, divide both sides by 4 to get "x" by itself:
x = 8/4 = 2

4x + 17 = 25
4x + 17 - 17 = 25 - 17
4x = 8
4x / 4 = 8 / 4
x = 8 / 4
x = 2
Now solve 3x - 21 = 45

4x+17=25
=>4x=8
=>x=2
so x=2
