Question

(15-9+8)-(a-b)+b=42,iar b si a sunt numere consecutive pare.

Answer 1

a= a, b= 2+ a.
14- (a- a-2)+ a+ 2= 42
14-a+a+2+a+2=42
18 + a= 42
a= 24
b= a+2= 26

Answer 2

a=b+2
14-(b+2-b)+b=42
14-2+b=42
12+b=42
b=42-12
b=30
a=30+2=32.
v;14-(32-30)+30=42
14-2+30=42
12+30=42.....sper ca te-am ajutat
