{{(x+3)*5+3]*5+3}*5+3=2343 descopera numarul care adunat cu.

Answer 1

{[(x+3)×5+3]×5+3}×5+3=2343

{[(x+3)×5+3]×5+3}×5=2343-3

{[(x+3)×5+3]×5+3}×5=2340

[(x+3)×5+3]×5+3=2340:5

[(x+3)×5+3]×5+3=468

[(x+3)×5+3]×5=468-3

[(x+3)×5+3]×5=465

(x+3)×5+3=465:5

(x+3)×5+3=93

(x+3)×5=93-3

(x+3)×5=90

x+3=90:5

x+3=18

x=18-3

x=15
