Răspuns :
ex1) calculati a+b in cazul in care ax+bx=100 si x=25
ax+bx=100
x(a+b)=100
25x=100
x=100/25
x=4
ex2) calculati2a+3b+c in cazul in care a+b=17 si b+c=18
2a+3b+c=2a+2b+b+c=2(a+b)+b+c=2*17+18=52
ax+bx=100
x(a+b)=100
25x=100
x=100/25
x=4
ex2) calculati2a+3b+c in cazul in care a+b=17 si b+c=18
2a+3b+c=2a+2b+b+c=2(a+b)+b+c=2*17+18=52
1)x(a+b)=25(a+b)=100,a+b=4
2)a+a+b+b+b+c=17+17+18=34+18=52
3)x:13=2r,x=2rx13=26r
4)abc:40=c+17,abc=40c+17
6)2abcd=abcd+1056,abcd=1056
5)=abab+aba+abb=al2bla2+ala2b+abla2
2)a+a+b+b+b+c=17+17+18=34+18=52
