lets just simplyfy al of them :)\nThe expression is : -3m -2 + 5m -8 =  2m-10\n\nThe expression is : 4(3a - 5) + 2(-3a + 7) = 12a-20 -6a +14\n                                                                       =6a-6\nThe expression is : 2/3(1/2x + 9) + 3 = x/3 + 6 +3 = x/3 +9\n\nThe expression is : x/4 - 1/8 - x/6 + 1/6 = x/12 + 1/24\n\nThe expression is : 2ab + a - ab - 7 = ab + a -7.\n\nso i would say,, The expression is : 2ab + a - ab - 7 is closest to being in its simplest form than the rest

Divide each side with the number before the variable. (8x = 72 , divide by 8 on each side).\n5. That's the answer.
