Question

a) daca 2a +3b+35=48 calculati 2a+3b+39 b) daca 2a+2b+17=36 calculati 6a+4b+47 c) daca 2a+5b+23=51 calculati 6a+15b+62 d) daca 3a+4b+2c= 32 calculati 8b+53+4c+6a

Answer 1

a)daca 2a +3b+35=48 calculati 2a+3b+39
2a+3b+35+4=48+4
2a+3b+39=52

b) daca 3a+2b+17=36 calculati 6a+4b+47
3a+2b+17=36
 6a+4b+34=72
6a+4b+34+13 =72+13=85

c) daca 2a+5b+23=51 calculati 6a+15b+62
2a+5b+23=51
6a+15b+69=153
6a+15b+69-7=153-7=146

d) daca 3a+4b+2c= 32 calculati
3a+4b+2c=32
6a+8b+4c=64
8b+53+4c+6a = 64+53=117
