-28 plus 9 = -19

43 + 19 = 62

45 -62 = -23

Answer 2

Answer:

$\mathbb\fcolorbox{purple} {pink}{- 9}$

Step-by-step explanation:

$45 - [43 - {9 - 4 (3 - 8 ÷ 2 + 6)}] \\= 45 - [ 43-{5(-5÷8)}] \\ = 45 - [ 43 -{9-4(3-4+6)} \\ = 45 - [ 43 -{9-4(3+2)}] \\ = 45 - [ 43 -{9-4(5)}] \\ = 45 - [ 43 -{9-20}] \\ = 45 - [ 43 - {-11}] \\ = 45 - (45+11) \\ = 45 - 54 \\ = -9$
