Question

Resuelve cada una de las siguientes ecuaciones lineales.


1) 6x = -24


2) 8y = 16


3) 5 / x = -2


4) – 6X = - 24


5) 5x - 2 = 3x + 4


6) x -7 =10​

Answer 1

1)

$6x = - 24 \\ x = \frac{ - 24}{6} \\ x = - 4$

2)

$8y = 16 \\ y = \frac{16}{8} \\ y = 2$

3)

$\frac{5}{x} = - 2 \\ x = ( - 2)(5) \\ x = - 10$

4)

$- 6x = - 24 \\ x = \frac{ - 24}{ - 6} \\ x = 4$

5)

$5x - 2 = 3x + 4 \\ 5x - 3x = 4 + 2 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

6)

x - 7 = 10

x = 10 + 7

x = 17
