You need to replace the x with 1 such that:
2+4[-3(1-6)+7*1]
Now solve from the inside out, according to the brackets and parenthesis, and by the multiplications, divisions, additions, and subtractions.
7*1 = 7
1-6 = -5
-3*-5 = 15
[15+7]=22
4*22=88
2+88=90
Your answer would be 90.
Just keep in mind the rules of how to do the operations.

x=12+4[-3(x-6)+7x]
x=12+4[-3x+24+7x]
x=12+4(4x+24)
x=12+16x+96
x=108+16x
-15x=108
x= -7.2
