Rozwiaz uklad rownan. tylko prosze was o dokladne rozwiazania. (x-1)² - (y-3)² = (x-y) (x+y) x+4/₂ - y+4/₃ = 1

a) x²-2x+1-(y²-6y+9)=x²+xy-xy-y² x²-2x+1-y²+6y-9=x²+xy-xy-y² x²-2x-y²+6y-x²-xy+xy+y²=9-1 -2x+6y=8 b) x+2-y+⁴/₃=1 x-y=1-⁴/₃ -2 x-y= ³/₃ - ⁴/₃ - ⁶/₃ x-y= - ¹³/₃ x-y= -4 ¹/₃

(x-1)² - (y-3)² = (x-y) (x+y) x+4/₂ - y+4/₃ = 1 x²-2x+1-(y²-6y+9)=x²-y² x+2-y+4/3=1 x²-2x+1-y²+6y-9=x²-y² x-y=1- 10/3 x²-2x-y²+6y-x²+y²=8 x-y=-7/3 -2x+6y=8 x=y-7/3 -2(y-7/3)+6y=8 x=y-7/3 -2y+14/3+6y=8 x=y-7/3 4y=8-14/3 x=y-7/3 4y=10/3 x=y-7/3 y=5/6 x=5/6-7/3 y=5/6 x=5/6-14/6 y=5/6 x=-9/6 y=5/6 x=-3/2
