​

Answer 1

Explicație pas cu pas:

[(15×a-35):4-27:3]=87×17754

[(15×a-35):4-27:3]=1.544.598

[(15×a-35):4-27]=1.544.598×3

[(15×a-35):4-27]=4.633.794

[(15×a-35):4]=4.633.794+27

[(15×a-35):4]=4.633.821

15a-35= 4.633.821×4

15a-35=18.535.284

15a= 18.535.284+35

15a=18.535.319

a=18.535.319:15

a=1.235.687,9333
