To solve, use pemdas. First, we'll start with the top, \(-8[(12-6)+3]+4\), subtract 12-6 as it's in parenthesis and inside the second pair of parenthesis, \(-8[(12-6)+3]+4=-8[6+3]+4\), now, add the 6 and 3 as they're in the last pair of parenthesis, \(-8[6+3]+4=-8[9]+4\), now multiply the -8 and 9 as they are touching via parenthesis, making them multiplied by each other, \(-8[9]+4=-72+4\), now add the 4 to -72, \(-72+4=-68\). Now, do the bottom. \(9-2(2+3)\), first add the 2 and 3, \(9-2(2+3)=9-2(5)\), then multiply the 2 and 5, \(9-2(5)=9-10\), now, subtract 9 and 10, \(9-10=-1\). Now, divide the top and bottom. \(\frac{-68}{-1} =68/1=68\).
