-3​

Answer 1

$\large\boxed{\begin{array}{l}\rm O\,valor\,de\,x\,que\,satisfaz\,a\,equac_{\!\!,}\tilde ao\\\rm 5x+2=2x-4\,\acute e:\\\rm a)-4\\\rm b)4\\\rm c)11\\\rm\!\!\!\!\checkmark d)\!-2\end{array}}$

$\Large\boxed{\begin{array}{l}\underline{\bf soluc_{\!\!,}\tilde ao\!:}\\\sf 5x+2=2x-4\\\sf 5x-2x=-4-2\\\sf 3x=-6\\\sf x=-\dfrac{6}{3}\\\\\sf x=-2\end{array}}$

Answer 2

Resposta: -2

Explicação passo-a-passo:

$5x + 2 = 2x - 4$

$5x - 2x = - 4 - 2$

$3x = - 6$

$x = \dfrac{ - 6}{3}$

x= -2
