Question

stiind ca a+b=196,calculeaza:

a+b+848=
528+a+b=
484+a+116+b=
b+38+2a+16+b=

Answer 1

Vom avea
1) = 196+848 = 1044
2) = 528 +196 = 724
3) = 600+ 196 = 796
4) = 2(a+b) + 54 = 2x196 +54 = 392 + 54 = 446

Answer 2

 a+b=196

a+b+848 = 196+848 =1044 ;  

528+a+b = 528+196 = 724 ;

484+a+116+b = 484+116+a+b = 484+116+196 = 796 ;

b+38+2a+16+b = 38+16+2(a+b)=54+2*196 = 446 ;
