Question

Valoarea lui a reprezinta distanta rutiera dintre Bucuresti si Madrid (749:7+10×40+324:3)+(345+812:2-921:3)+a=4402.

Answer 1

(749:7+10×40+324:3)+(345+812:2-921:3)+a=4402
(107+ 400 + 108) + ( 345 + 406 - 307) + a = 4 402
 615 + 444 + a = 4 402
 1 059 + a = 4 402
   a= 4 402 - 1 059
   a=3 343 

Answer 2

(749;7+10x40+324:3)+(345+812:2-921:3)+a=4402
(107+400+108)+(345+406-307)+a=4402
(507+108)+(751-307)+a=4402
=615+444+a=4402
=1059+a=4402
a=4402-1059
a=3343  distanta dintre Bucuresti si Madrid
