Question

se stie ca:a=42-5x8-1;b=(2x3+2x2):5;c=5x2:10+2x1,aflati:2a+2b+2c si 3c-2a-b

Answer 1

a=42-40-1
a=2-1
a=1
b=(6+4):5
b=10:5
b=2
c=10:10+2
c=1+2
c=3
2a+2b+2c
(1*1)+(2*2)+(3*3)=
1+4+9=
5+9=
14
3c-2a-b
(3*3*3)+(1*1)+2=
(9*3)+1+2=
27+1+2=
28+2=
30

Answer 2

a=42-5x8-1
a=2-1
a=1
b=(2x3+2x2):5
b=(6+4):5
b=10:5
b=2
c=5x2:10+2x1
c=10:10+2
c=1+2
c=3
aflati 2a+2b+2c
21+22+23=43+23=66
aflati 3c-2a-b
33-21-2=12-2=10
