Question

Encontrar el valor de x en cada ejercicio

Answer 1

Respuesta:

a) x = 1

b) x = 8

c) x = 3

d) x = -6

e) x = 17

Explicación paso a paso:

a) 6x + 4 = 10

6x = 10 - 4

6x = 6

x = 6/6

x = 1

b) 1/2 x = 4

x = 4.2/1

x = 8

$c) \: 3 {x}^{2} - 27 = 0 \\ 3 {x}^{2} = 27 \\ {x}^{2} = \frac{27}{3} \\ {x}^{2} = 9 \\ x = \sqrt[2]{9} \\ x = 3$

d) 2x = 4x + 12

-12 = 4x - 2x

-12 = 2x

-12/2 = x

-6 = x

x = -6

$e) \: {x}^{2} = 289 \\ x = \sqrt[2]{289} \\ x = 17$
