Question

x/2 + x/4 + x/2 = 2 qual a resposta ? fvr colocar calculo

Answer 1

$\dfrac{x}{2} + \dfrac{x}{4}+ \dfrac{x}{2} =2\\\\ MMC~de~~(2~e~4)=4\\\\ \dfrac{2\cdot x+1\cdot x+2\cdot x}{4} = \dfrac{8}{4} \\\\ \dfrac{2\cdot x+1\cdot x+2\cdot x}{\not4} = \dfrac{8}{\not4}\\\\ 2x+x+2x=8\\\\ 5x=8\\\\ \huge\boxed{x= \dfrac{8}{5}}$
