Question

e) 3365,79-[ (48,16+573)-( 2403-2072,96)]=

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

Answer 1

Răspuns:

3365,79-(621,16-330,04)=

3365,79-291,12=3074,67

13,02+y=547,1

y=547,1-13,02

y=534,08

2y-108,09=y+28,25

2y-y=108,09+28,25

y=136,34
