Řešení soustavy rovnic
Řeš v ℝ × ℝ soustavu rovnic:
x\ –\ 2 = 2(1\ –\ 2y) + 1
\large 5 x + 3\left( y + 1\right) = 4\left( x + 2\right) -y
\large K = \left \{ {\left[ {x;\Large \frac{{5+x}}{4}\large } \right] ;x \in \mathbb{R}} \right \}
\large K = \left \{ {\left[ {x;\Large \frac{{5-x}}{4}\large } \right] ;x \in \mathbb{R}} \right \}
\large K = \left \{ {\left[ {x;\Large \frac{{5-x}}{3}\large } \right] ;x \in \mathbb{R}} \right \}
\large K = \left \{ {\left[ {x;\Large \frac{{5-x}}{5}\large } \right] ;x \in \mathbb{R}} \right \}
