Question

calculeaza valorile a,b,c,d,stiind ca;

a+a=b,b+b=c, c+c=d,d+6=30

Answer 1

2a=b, 2b=c, 2c=d, d+6=30, d=30-6=24, c=d/2=24/2=12, b=c/2=12/2=6, a=b/2=6/2=3

Answer 2

2a = b ; 2b = c ; 2c = d

d + 6 = 30 => d = 30 - 6 = 24

c = d/2 => c = 24/2 = 12

b = c/2 => b = 12/2 = 6

a = b/2 => a = 6/2 = 3
