Answer 1

esta es la respuesta paso a paso

Answer 2

Respuesta:

1. x=4

2. x=13/5

Explicación paso a paso:

1. 6x(x-3)+20=8-3x(5-2x)

$6x^{2} - 18x + 20 = 8 - 15x + 6x^{2}\\6x^{2} - 6x^{2} - 18x + 15x + 20 - 8 = 0\\-3x + 12 = 0\\-3x = -12\\(-1) -3x = -12 (-1)\\3x = 12\\x= \frac{3}{12}\\x= 4$

2.  5/3(x-5/2)-3/5=x-41/10

$\frac{5}{3}x - \frac{25}{6} - \frac{3}{5} = x - \frac{41}{10} \\\\\frac{5}{3}x - \frac{35}{6} = x - \frac{41}{10}\\\\\frac{5}{3}x - x = \frac{35}{6} - \frac{41}{10}\\\\\frac{2}{3}x = \frac{26}{15}\\\\x= \frac{25}{15}/\frac{2}{3}\\\\x= \frac{78}{30}\\\\simplifica\\\\x= \frac{13}{5}$
