ok
Explicație pas cu pas:
a) 282x356-(121000-25872)x(100-99)=a+281x0-4736
100392-95128x1=a+281x0-4736
5264=a+281x0-4736
a=5264-281x0-4736
a=4983x0-4736
a= -4736
b) 1000000-(1000-750-245)x(472321+b+214272)=70888
1000000-1xb-258049=70888
999999xb-258049=70888
b=741950-70888
b=671062
c) 342999+c-246x[4+6x(294462-294000)-2000]=269214
342999+c-246x(4+6x462-2000)=269214
342999+c-246x(10x462-2000)=269214
342999+c-246x(4620-2000)=269214
342999+c-246x2620=269214
342999+c-644520=269214
c= 342999+644520-269214
c=987519-269214
c=718305
Sper ca te-am ajutat, succes la teme :) ( voi ati invatat axa negativa?)
