Question

[ (64 x 33 x 2 : 4 - 500 x 2) :2 +5 x a ] - 6 x 12 + 999 : 9 =112 ,va rog se poate sa ma ajute cineva.ms.mult

Answer 1

[(2112x2:4-1000):2+5xa]-6x12+111=112

[(4224:4-1000):2+5xa]-72+111=112

[(1056-1000):2+5xa]-72+111=112

(56:2+5xa)-72+111=112

(28+5xa)-72=112-111

                    =1

28+5xa=72+1

              =73

5xa=73-28

      =45

a=45:5

a=9
