Question

resolver ejercicios de ecuaciones ​

Answer 1

$[tex]4. \: \: 5x - \frac{1}{2} = x + \frac{9}{2} \\ 5x - x = \frac{9}{2} + \frac{1}{2} \\ 4x = 5 \\ x = \frac{5}{4} \\ \\ 5. \: \: \: \frac{3x}{5} + \frac{17}{5} = \frac{x}{5} + \frac{21}{3} \\ \frac{3x}{5} + \frac{17}{5} = \frac{x}{5} + 7 \\ 3x + 17 = x + 35 \\ 3x - x = 35 - 17 \\ 2x = 18 \\ x = 9$[/tex]
