Question

resolver esta ecuacion 1) x-(2x+1) = 8 -(3x+3)

Answer 1

Respuesta:

x=3

Explicación paso a paso:

X-(2x+1)=8-(3x+3)

x-2x-1=8-3x-3

-x-1=5-3x

3x-x=5+1

2x=6

x=3

Answer 2

$x - (2x + 1) = 8 - (3x + 3) \\ x - 2x - 1 = 8 - 3x - 3 \\ - x - 1 = 5 - 3x \\ - x + 3x = 5 + 1 \\ 2x = 6 \\ x = \dfrac{6}{2} = 3$

Verificando:
$3 - (2(3) + 1) = 8 - (3(3) + 3) \\ 3 - (6 + 1) = 8 - (9 + 3) \\ 3 - 7 = 8 - 12 \\ - 4 = - 4$
