Question

A+B=C
D-C=A
D-B=A2
B=3/4 dari D
D=akar dari 16
Berapakah nilai C?

Answer 1

D = akar 16 --> D = 4
B = 3/4 D --> (3/4) x 4 --> B = 3
D - B = A2 --> 4 - 3 = A2 --> A = 1/2
D - C = A --> C = D - A = 4 - 1/2 --> (8/2) - (1/2) = 7/2

D = 4, C = 7/2, B = 3, A = 1/2

Answer 2

D =
D = 4
B = D
B =  x 4 
B = 3
D - B = A2
 4 - 3 = A2
A =
D - C = A
C = D - A
C = 4 - = - =

jadi:
D = 4,
C = ,
B = 3 ,
A =
