Question

Efectue: 5x + 3 - {3x + 4 - (8 - 5x)}​

Answer 1

$5x + 3 - (3x + 4 - (8 - 5x))\\\\5x+3-(3x+4-8+5x)\\\\5x+3-(8x-4)\\\\5x+3-8x+4\\\\-3x+7$

Answer 2

Respuesta:

$=7x-1$

Explicación paso a paso:

$5x+3-3x+4-\left(8-5x\right)$

$=-\left(8-5x\right)+5x-3x+3+4$

$=-\left(8-5x\right)+5x-3x+7$

$=-\left(8-5x\right)+2x+7$

$=-8+5x+2x+7$

$=5x+2x-8+7$

$=5x+2x-1$

$=7x-1$
