x/2 + 6 = x - 9

x - x/2 = 15 

x/2 = 15 

x = 30 

-----------------------------------------------------------------

(x + 2)/2 + (x + 5)/3 = 7 

mmc(2,3) = 6

3*(x + 2) + 2*(x + 5) = 42

3x + 6 + 2x + 10 = 42

5x = 42 - 16 = 26 

x = 26/5 

-----------------------------------------------------------------

(x + 2)/2 - (x + 5)/3 = 7

mmc(2,3) = 6

3*(x + 2) - 2*(x + 5) = 42

3x + 6 - 2x - 10 = 42

x = 42 + 4 = 46
