d) (14,7-1,68)+y= 593-45,9 e) 2y-(39,6+68,49) = y + ( 83-54,75)

Answer 1

Răspuns:

a)x-3=12,7 ;x=12,7+3;x=15,7

b)x+15,9=20;x=20-15,9;x=4,1

c)56,5-x=(24,5-13)+x;56,5-x=11,5+x;56,5-11,5=x+x;45=2x;x=45÷2;x=22,5

d),e) scuze dar nu mai am timp,sper ca te am ajutat macar unic si sper ca am facut bine
