Y echish: 6y-x=8 x=6* -8=  -8= -2  .

x+13y=8

19y=16; y=  J: (-2 ;  )

3. 
   Yangi mavzuning bayoni.
   

Yechish: 1) (x+3)²= (x-3)² 3) (x+6)²=(x+10)²

x²+6x+9= x²-6x+9 x²+12x+36= x²+20x+100

12x=0; x=0. -8x=64; x= -8.

2) (1-x)²= (x+2)² 4) (x+5)²= (x-7)²

1-2x+x²= x²+4x+4 x²+10x+25= x²-14x+49

-6x=3; x= -0,5. 24x=24; x=1.

Yechish: 1) x₁=4; x₂=-1. 2) x₁= ; x₂=1. 3) x₁=7; x₂= -11.
