Okay well start out by breaking it up. You know that this equation is equivalent: 1/3x+1/3x+1/3(2)=x+5, so 2/3x+2/3=x+5. From here its easy, put x's on one side the solve for x.

Firstly time both sides by 3 to make it easier(whole numbers)
2x + 2 = 3x- 15
Then add 15 to both sides(to get rid of one of the varibles from one side)
2x + 17 = 3x
Then minus 2x from both sides (to get rid of one of the varibles from the other side)
17 = x
Then to make sure, feed the answer back into the original formulae
1/3(17+17+2) = 17 - 5
1/3(36) = 12
12 = 12 (your answer is correct)
x = 12

1/3(x+x+2)=x-5
1/3(2x + 1) = x - 5
2x/3 + 1/3 = x - 5
2x/3 = x - 5 - 1/3
2x/3 - x = -5-1/3
(2x - 3x)/3 = (-15 - 1)/3
-x/3 = -16/3
-x = -16 (Two equal denominators cancel each other out)
x = 16 (The minus signs cancel each other out)

1/3x+1/3x +2/3 = x-5
2/3x + 2/3 = x - 5
2/3x - x = -5 - 2/3
-1/3x = -5 2/3
1/3x = 5 2/3
x = 3 x 5 2/3
x = 17
