Determine 2538

Juraj, Milan, and Adrian have a total of 93 soldiers. Juraj has three more soldiers than Milan. Adrian has 15 more soldiers than Milan. Determine how much each one has.

Correct answer:

J =  28
M =  25
A =  40

Step-by-step explanation:


J+M+A = 93
J = 3+M
A = M+15

A+J+M = 93
J-M = 3
A-M = 15

Row 3 - Row 1 → Row 3
A+J+M = 93
J-M = 3
-J-2M = -78

Row 3 + Row 2 → Row 3
A+J+M = 93
J-M = 3
-3M = -75


M = -75/-3 = 25
J = 3+M = 3+25 = 28
A = 93-J-M = 93-28-25 = 40

A = 40
J = 28
M = 25
