A:B=97 rest 21
A-B=5397
A=97B+21
97B+21-B=5397
96B=5397-21
96B=5376
B=5376:96
B=56

A:56=97 rest 21
A=56×97+21
A=5453
(4A-B:14):8=(4×5453-56:14):8=(21812-4):8=21808:8=2726

A:B=97 REST 21

A=(B X 97) + 21

A-B = 5397

B X 97 + 21 - B = 5397

B X 97 - B = 5397 - 21

96 XB = 5376

B = 5376:96

B= 56

A = 56X97+21

A=5432+21

A=5453

(4A-B:14):8=

(4X5453 - 56:14):8=

(21812-4):8=

21808:8=2726
