You can
put this solution on YOUR website! 7-1/2x=3
I can't tell whether you meant
1
7 - --- x = 3
2
or whether you meant
1
7 - ---- = 3
2x
------------------------------------------
If you meant the first one you should have typed
7 - (1/2)x = 3
If you meant the second one you should have typed
7 - 1/(2x) = 3
-------------------------------------------
If you meant
1
7 - --- x = 3
2
Then multiply every term on both sides by LCD = 2
1
(2)7 - (2)--- x = (2)3
2
14 - x = 6
Add -14 to both sides
14 - x = 6
-14 -14
-----------------
-x = -8
Divide both sides by -1
-x -8
------ = ----
-1 -1
x = 8
-------------------------------------
If you meant
1
7 - ---- = 3
2x
Then multiply every term on both sides by LCD = 2x
1
(2x)7 - (2x)---- = (2x)3
2x
14x - 1 = 6x
Add 1 to both sides
14x - 1 = 6x
+ 1 + 1
----------------------
14x = 6x + 1
Add -6x to both sides
14x = 6x + 1
-6x -6x
----------------
8x = 1
Divide both sides by 8
8x 1
------ = ---
8 8
1
x = ---
8
