Question

-(5x+3)-(7x+2(-x-3))=-3(x+2)

Answer 1

Respuesta:

-9/13

Explicación paso a paso:

$-(5x+3)-(7x+2(-x-3))=-3(x+2) \\ - (5x) - ( + 3) - (7x + 2( - x) + 2( - 3)) = - 3(x) - 3(2) \\ - 5x - 3 - (7x - 2x - 6) = - 3x - 6 \\ - 5x - 3 - (5x - 6) = - 3x - 6 \\ - 5x - 3 - (5x) - ( - 6) = - 3x - 6 \\ - 5x - 3 - 5x + 6 = - 3x - 6 \\ - 5x - 5x - 3 + 6 = - 3x - 6 \\ - 10x + 3 = - 3x - 6 \\ 10x + 3x = - 6 - 3 \\ 13x = - 9 \\ x = \frac{ - 9}{13}$

Answer 2

Explicación paso a paso:

-(5x+3)-(7x+2(-x-3))=-3(x+2)

-(5x+3)-(7x-2x-6)=-3(x+2)

-(5x+3)-7x+2x+6=-3x-6

-5x-3-7x+2x+6=-3x-6

-5x-7x+2x+3x=-6-6+3

-12x+5x=-9

-7x=-9

x=-9/-7

x=9/7
