Answer 1

1. a= 5414-2456

a= 2958

b=8121-4698

b=3423

c=1983+2657

c=4640

d=7569-3256

d=4313

2.a) a+6289=9545

a=9545-6289

a= 3256

b) a-b=3542

a-(3542+1023)=3542

a-4565=3542

a=3542+4565

a=8107

c)7381-a=2986

a=7381-2986

a=4395

d) a-1278=2187

a=2187+1278

a=3465

3. a+2416<2420

a+2416=2417/2518/2419

a=1,2,3

a-4997<5

a-4997=4,3,2,1,0

a= 4997;4998;4999;5000;5001

4. a-b=1645

2694-b=1645

b=2694-1645

b=1049

5.a+b+c=8264

a+b=6327

c=a-1548

6327+c=8264

c=8264-6327

c=1937

a=1937-1548

a=389

b=6327-389

b=5938

verificare: a+b+c=8264

389+5939+1937=8264

Answer 2

Explicație pas cu pas:

1)2.456+a=5.414

a=5.414-2.456

a=2.957

8.121-b=4.698

b=4.698+8.121

b=12.819

c-2.657=1.983

c=1.983+2.657

c=4.640

d+3.256=7.569

d=7.569-3.256

d=4.313

2).

a).a+6.289=9.545

a=9.545-6.289

a=3.256

3).a+2.416<2.420

a<2.420-2.416

a<4

a-4.997<5
