My name is that but I need a answer check for "all my X's quiz" for math 7A
-7+6 (x-8/2) -2(x+3) +10
= -7 + 6x - 6*8/2 - 2x - 2(3) + 10
= -7 + 6x - 24 - 2x - 6 + 10
= (6-2)x + (-7-24-6+10)
= 4x - 27
Hmmm. Not there. Could you have been careless with parentheses, and meant
-7+6 ((x-8)/2) -2(x+3) +10 = x=27 ?? Nope.
Guess you better figure out what the expression really is.
