Question

- ( x + 8 ) = 2 ( 4x + 5)​

Answer 1

-(x + 8) = 2(4x + 5)​

-x - 8 = 8x + 10

-x = 8x + 10 + 8

-x = 8x + 18

-x - 8x = 18

-9x = 18

x = 18/-9

x = -2

Answer 2

• x = 2

Explicación paso a paso:

• -(x + 8) = 2 (4x + 5)
• -(x + 8) = 8x + 10
• -x + -8 = 8x + 10
• -x + -8x = 10 + 8
• -9x = 18
• x = 18/9
• x = 2
