Question

Hallar el valor de x en las siguientes ecuaciones. a) x + 5 = 14 b) x – 3 = -8 c) 2.x + 9 = +1 d) 3+x−2 = 3+1 e) 5+x = 1- x

Answer 1

Respuesta:

a) X = 9

b) X = -5

c) X = -4

d) X = 3

e) X = -2

Explicación paso a paso:

a) x = 14 -5 = 9

b) x = -8+3 = -5

c) 2x = -9 +1

2x = -8

x = -8/2 = -4

d) 3 + x - 2 = 3 + 1

3 -2 + x = 4

1 + x = 4

x = 4 - 1 = 3

e) 5 + x = 1 - x

x + x = 1 - 5

2x = -4

x= -4/2 = -2
