Question

Suma a 2 nr. Este de 3 ori mai mare ca diferenta lor. Afla-le stiind ca daca as aduna suna cu diferenta as obtine 92.

Answer 1

a + b = 3(a - b)
a + b + a - b = 92
2a = 92
a = 92 : 2
a = 46
a + b = 3a - 3b
4b = 2a
4b = 2 * 46
4b = 92
b = 92 : 4
b = 23

Answer 2

a+b=3(a-b)

a+b+a-b=92

2a=92

a=46

46+b=3(46-b)

b+3b=-46+3*46

4b=92

b=92/4

b=23

Deci a=46 si b=23.
