a) 1a4b

1+4+a+b = 10

1 + 4 = 5 =>

a + b = 5

a si b - orice număr mai mic sau egal cu 5

• a = 0 => b = 5

• a = 1 => b = 4

• a = 2 => b = 3

• a = 3 => b = 2

• a = 4 => b = 1

• a = 5 => b = 0

b ) 1a4b

1 × 4 × a × b = 12

1 × 4 = 4

a : b = 12 : 4

a × b = 3

• a = 1 => b = 3

• a = 3 => b = 1
