Question

Ejercicio: Resuelve las siguientes ecuaciones
Ecuación
2x+20=12
3x-27=13
5(x-2)=45
-4x+40=4
x/6+25=50​

Answer 1

Respuesta:

$2x + 20 = 12\\\\2x = 12 - 20\\\\2 x = - 8\\\\x= \frac{-8}{2}\\\\x= - 4 \\\\\\\\3 x - 27 = 13\\\\3 x = 13 + 27\\\\3 x = 40\\\\x = \frac{40}{3}\\\\\\5( x - 2 ) = 45\\\\5 x - 10 = 45\\\\5 x = 45+ 10\\\\5 x = 55\\\\x=\frac{55}{5}\\\\x= 11$

$-4 x + 40 = 4\\\\- 4 x = 4 - 40\\\\- 4 x = -36\\\\x = \frac{-36}{-4}\\\\x= 9\\\\\\\frac{x}{6} + 25 = 50\\\\\frac{x}{6}= 50 - 25\\\\\frac{x}{6}= 25\\\\x = 25 * 6\\\\x = 150$
