Question

(2 + x)/(4 + x) = 3/4 socorooooooooo alguem me ajudarrrr​

Answer 1

Resposta:

x=4

Explicação passo a passo:

$\frac{(2+x)}{(4+x)} =\frac{3}{4}$   ⇒ 4*( 2+x) = 3*(4+x) ⇒ 8+4x= 12 +3x ⇒ 4x - 3x= 12-8 ⇒ x = 4

Answer 2

$\Large\mathsf\displaystyle{} \dfrac{\left(2 + x\right)}{\left(4 + x\right)} = \dfrac{3}{4} \\\\\Large\mathsf\displaystyle{} \dfrac{2 + x}{4 + x} = \dfrac{3}{4},x \cancel{ = } - 4 \\ \\ \\ \Large\mathsf\displaystyle{}4\left(2 + x\right) = 3\left(4 + x\right) \\ \Large\mathsf\displaystyle{}8 + 4x = 12 + 3x \\\Large\mathsf\displaystyle{}4x - 3x = 12 - 8 \\\Large\mathsf\displaystyle{}x = 4,x\cancel{ = } - 4 \\ \Large\mathsf\displaystyle{}x = 4$

Solução:

$\bm\Large\begin{gathered} \begin{gathered}\large \overline{ \boxed{\boxed{ \begin{array}{r}\mathsf{ x = 4 }\end{array}}}} \end{gathered}  \end{gathered}$

$\bm\Large\begin{gathered} \begin{gathered}\large \overline{ \boxed{\boxed{ \begin{array}{r}\mathsf{\red{Bons~Estudos} }\end{array}}}} \end{gathered}  \end{gathered}$
