Rovnice s dvoma premennými
Rieš v \( ℝ × ℝ \) sústavu rovníc:
\( (x + 3)(y + 5) = (x + 1)(y + 8) \)
\( \normalsize\left(2x-3\right)\left(5y+5\right)=2\left(5x-6\right)\left(y+1\right) \)
\( \large K=\left\{\left[\frac{3}{5};-1\right]\right\} \)
\( \large K=\left\{\left[\frac53;-1\right]\right\} \)
\( \large K=\left\{\left[\frac{5}{3};0\right]\right\} \)
\( \large K=\left\{\left[\frac{5}{2};-1\right]\right\} \)
