-3 + { 1 – 3[20 + 2(-6 – 7)]}
SIMPLIFY ANSWER:

16

Step-by-step explanation:

To simplify, we have to start from the innermost parentheses and expand from there!

-3+{1-3[20+2(-6-7)]}  -6-7=-13

-3+{1-3[20+2(-13)]}    2*-13=-26

-3+{1-3[20-26]}          20-26=-6

-3+{1-3[-6]}                 -3*-6=18

-3+{1+18}                     1+18=19

-3+19                           -3+19=16
