Question

A=bx2, b=c-14, c=d+15, e=d:3, d-e=44. cat este a, b, c, d, e ?

Answer 1

a = b x 2
b = c - 14
c = d + 15
e = d : 3
d -e = 44 
d - d : 3 = 44
3d - d = 132
2d = 132
d = 66
e = 66 : 3
e = 22
c = d + 15
c = 66 + 15
c = 81
b = c - 14
b = 81 - 14
b = 67
a = b x 2
a = 67 x2
a = 134
numerele sunt:
a = 134
b = 67
c = 81
d= 66
e =22
