Resolva:

$\large\rm{\dfrac{3x}{4}=2x+5}$​

Answer 1

Resposta:

x = -4

Explicação passo a passo:

3x/4 = 2x + 5

3x/4 - 2x = 5

3x - 8x = 20

-5x = 20

5x = -20

x = -4

Conferindo

x = -4

-12/4 = -8 + 5

-3 = -3

Answer 2

$\Large\boxed{\begin{array}{l}\sf\dfrac{3x}{4}=2x+5\\\sf3x=8x+20\\\sf3x-8x=20\\\sf-5x=20\\\sf x=-\dfrac{20}{5}\\\huge\boxed{\boxed{\boxed{\boxed{\sf x=-4}}}} \end{array}}$
