Question

Resolver las siguientes ecuaciones e inecuaciones
3X+7=2X+17
5.(3X+1)=10X -45
6+8X+3>10X+19
7X+1= -3X+21

Answer 1

Respuesta:

$3x + 7 = 2x + 17\\\\3x - 2x = 17 - 7\\\\x = 10$

**********************

$5 ( 3x + 1 ) = 10 x - 45\\\\15 x + 5 = 10 x - 45\\\\15 x - 10 x = - 45 - 5\\\\5 x = - 50\\\\x = \frac{-50}{5}\\\\x = - 10$

*********************

$6 + 8 x + 3 > 10 x + 19\\\\8 x - 10 x > 19 - 6 - 3\\\\- 2 x > 19 - 9\\\\- 2 x > 10\\\\x >\frac{10}{-2}\\\\x> -5$

**********************

$7 x + 1 = -3x + 21\\\\7 x + 3 x = 21 - 1\\\\10 x = 20\\\\x = \frac{20}{10}\\\\x = 2$
