first simply the () and then the [] so and then solve the rest
6[5(-6)-1]+2/7(6)+4
6[-30-1]+2/42+4
6[-31]+2/42+4
-186+2/46
-184/46 = -4

Just solve in the order of PEMDAS: (for multiplication and division, it is left to right. It does not have to be multiplication first. Same thing with addition and subtraction.) 

Parenthesis- solve what's inside parentheses
Exponents- solve those with exponents
Multiply(or divide)*- solve
Divide(or multiply)*- solve
Add(or subtract)*- solve
Subtract(or add)*- solve

*whichever comes first in the equation: 
ex. 7-5(3+5)+4
7-5(8)+4
7-40+4
In this case, subtraction is first, sooo... -33+4
End result.... -29  !!!!! =D
