Question

Resolvendo a equação 2x + 8 = 4x + 11, obtém:

Answer 1

Olá!

$2x + 8 = 4 \times + 11$

Juntamos os termos semelhantes:

$2x - 4x = 11 - 8$

$- 2x = 3$

$x = \frac {3}{ - 2}$

Assim, o resultado é 3/–2 ou –1,5

Answer 2

$\sf 2\cdot(X+4)=4x+11\\\\\\2x+8=4x+11\\\\\\{Subtrair\:}8{\:de\:ambos\:os\:lados}\\\\\\2x+8-8=4x+11-8\\\\\\2x=4x+3\\\\\\2x-4x=4x+3-4x\\\\\\-2x=3\\\\\\\dfrac{-2x}{-2}=\dfrac{3}{-2}\\\\\\\to \boxed{\sf x=-\frac{3}{2} \approx-1,5}$
