that's so easy :) its 3 or -1\3

6 - 2 = 4
|3g-5| = 4
4 + 5 = 9
3g = 9
9 \ 3 = 3

and you just invert it cuz its the absolute value. which is -1\3

hope that helped :)

|3g - 5| - 2 = 6 = |3g - 5| = 8 => 3g - 5 = 8 => g = 13/3 or -3g + 5 = 6 => -3g = 1 => g = -1/3

|3g - 5| = 6 - 2
|3g - 5| = 4
3g = 4 + 5
3g = 9
g = 3

I 3g - 5 I = 4

3g - 5 = 4 or 3g - 5 = - 4
3g = 9 , 3g = 1
g = 3 , g = 1/3

Actually when dealing with absolute value, there are almost always 2 answers. In this case g could be 3 or 1/3. |3(3)-5|=4 or |3(1/3)-5|=4. The only time an absolute value equation doesn't have two answers is when the numbers in the absolute value equal 0. It can also be no solution if it equals a negative number.

Hey,
First subtract 2
|3g - 5|=4
In order to get rid of the abs. value you have to account for both possibilities.
-4=3g - 5=4
Solve. Remember what ever you don to one side you have to do to all sides.
You should get two answers.

Hope this Helps. ^_^

|3g - 5| + 2 = 6
|3g - 5| = 6 - 2
|3g - 5| = 4
3g = 4 + 5
3g = 9
g = 9 / 3
g = 3

I3g - 5I +2 = 6
|3g - 5| = 6 - 2
3g + 5 = 4
3g = 4 - 5
3g = -1
g = -1/3
2010-12-10 4:34 pm
|3g-5| +2 = 6
3g + 5 +2 =6
3g +7= 6
3g= -1
g= -1/3
參考: I tried.

g = 3
