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