Question

sustitución e igualación de las ecuaciones 2x+3y=13 4x+5y=23

Answer 1

$\frac{x}{y} \sqrt[n]{x} \sqrt{x} \sqrt[n]{x} \frac{x}{y} x_{123} x^{123} \leq \geq \sqrt{x} \int\limits^a_b {x} \, dx \sqrt{x} x^{2} \sqrt[n]{x} \left \{ {{y=2} \atop {x=2}} \right. \sqrt{x} \sqrt[n]{x} \left \{ {{y=2} \atop {x=2}} \right.$
