Answer 1

Răspuns:

b. 2143+b+53204=84201

Explicație pas cu pas:

b=84.201-2.143-53.204

b=28.854

verificare 2.143+28.854+53.204=84.201

3417-b+24515=26.515

b=26.515-3.417-24.515

b=1.417

verificare 3.417-1.417+24.515=26.515

(2.000+24.515=26.515)

4.195+b+43.219=49.824

b=49.824-4.195-43.219

b=2410

verificare: 4.195+2.410+43.219=49.824

d. b+1.475+23.412=71.315

b=71.315-1.475-23.412

b=46.428

verificare:46,428+1475+23.412=71.315

b-1.890-14.789=32.456

b=32.456+1.890+14.789

b=49.135

verificare:49.135-1.890-14.789=32.456
