Rovnice s dvoma neznámymi
Rieš v \( ℝ × ℝ \) sústavu rovníc:
\( x\ –\ 2 = 2(1\ –\ 2y) + 1 \)
\( \normalsize5x+3\left(y+1\right)=4\left(x+2\right)-y \)
\( \large K=\left\{{\left[{x;\frac{{5-x}}{2}}\right];x\in\mathbb{R}}\right\} \)
\( \large K=\left\{{\left[{x;\frac{{5-x}}{4}}\right];x\in\mathbb{R}}\right\} \)
\( \large K=\left\{{\left[{x;\frac{{5+x}}{4}}\right];x\in\mathbb{R}}\right\} \)
\( \large K=\left\{{\left[{x;\frac{{5-x}}{3}}\right];x\in\mathbb{R}}\right\} \)
