Question

[tex]решите систему уровнений (х-1)^-(х+2)^=9у и (у-3)^-(у+2)^=5х

Answer 1

$begin{cases} (x-1)^2-(x+2)^2=9y\ (y-3)^2-(y+2)^2=5x end{cases}\ begin{cases} -2x+1-4x-4=9y\ -6y+9-4y-4=5x end{cases}\ begin{cases} -6x-3=9y\ -10y+5=5x end{cases}\ begin{cases} 2x+3=-3y\ 2y-1=-x end{cases}\ begin{cases} x=1-2y\ 2(1-2y)+3=-3y end{cases}\ begin{cases} x=-9\ y=5 end{cases}$
