Question

Rezolvati va rog frumos

Answer 1

1) y=2x                             y=2x                      y=2x           y=2x
    -4x²+4x*2x+32=0          -4x²+8x²=-32         4x²=-32      x²=-8
S=∅
2)Scadem din prima ecuatie ecuatia a doua
   -6x=-12                         x=2                       x=2                  x=2
    5x+3y=-5                      10+3y=-5             3y=-15             y=-5
S={(2;-5)}
