Question

3x+2 sobrex + 1 = 5 sobre 2

Answer 1

Resposta:

x = 1

Explicação passo a passo:

$\frac{3x+2}{x+1} =\frac{5}{2} \\\\\frac{3x+2}{x+1}(\frac{2}{5} ) =\frac{5}{2} (\frac{2}{5} )\\\\\frac{2(3x+2)}{5(x+1)} =\frac{2(5)}{5(2)} \\\\\frac{6x+4}{5x+5} =\frac{10}{10} \\\\\frac{6x+4}{5x+5} =1\\\\\frac{6x+4}{5x+5}(5x+5) =1(5x+5)\\\\6x+4=5x+5\\\\6x-5x=5-4\\\\\bold{x=1}$
