You were already given the correct answer twice, but as they say, the third time's a charm!
3x+5=22
To begin isolating the variable, our first step is to subtract five from both sides.
3x+5=22
-5 -5
Which gives you...
3x=17
To completely isolate the variable to find our answer, we need to divide both sides by three.
3x/3=17/3
Thus, x=17/3.
Check:
x=17/3
Replace x in the equation with 17/3 to check.
3(17/3)+5=22
Both three's cancel out.
17+5=22
22=22
All good. :D
**Sorry! Yahoo! won't let me modify the spacing, it seems, to show that you subtract the five from both sides, not from the 3x and 5. XD

3x+5 = 22
-5 -5
3x = 17
3/3x = 17/3
x=17/3
x=5 2/3
Check this
3(17/3) +5 =22
3/1(17/3) +5 =22
51/3 +5 = 22
17+5=22
22 = 22
answer x=5 2/3 or x=17/3 checks and is correct answer

subtract 5 from both sides to get
3x+5 -5 = 22 -5 3x = 17
divide both sides by 3 to get
3x/3 = 17/3 so x=17/3

first add -5 to both sides ,
3x+5-5=22-5
3x=17
then divide both sides by 3
3x/3=17/3
so your ansawer is
x=17/3

3x + 5= 22
-5 -5 (subtract 5 from both sides
--------------------
3x= 17
divide by 3 for both sides
x= 17/3
