Question

45: n = (3 045 - 426 x 7-3x9): 4 72:9 = (n - 395 x 6-9 x 9): 6 56: 8 = (3 334 - 403 x 8 - 6 x 9): n​

Answer 1

sper că le am împărțit bine

45: n = (3 045 - 426 x 7-3x9): 4

45:n=(3045-2982-27):4

45:n=(63-27):4=36:4=9 /:9

5:n=1 n=5

72:9 = (n - 395 x 6-9 x 9): 6

8=(n-9370-81):6

8=(n-9289):6

8×6=n-9289

n=48+9289

n=9337

56: 8 = (3 334 - 403 x 8 - 6 x 9): n

7=(3334-3224-54):n

7n=110-54=56

n=56:7=8

n=8
