Question

x-1/2 + x-3/3 = 6 Pessoal me ajudem por favor

Answer 1

$\texttt{Primeiro organize o lado esquerdo da igualdade:}\\\\\\x- \dfrac{1}{2}+x-\dfrac{3}{3}\\\\\\=2x-\dfrac{1}{2}-\dfrac{3}{3}~~(reduza~as~fra\c{c}\~oes~ao~mesmo~denominador)\\\\\\=2x-\dfrac{3}{6}- \dfrac{6}{6}\\\\\\=2x-\dfrac{9}{6}~~(simplifique~a~fra\c{c}\~ao)\\\\\\=2x-\dfrac{3}{2}\\\\\\\texttt{Refazendo a igualdade:}\\\\\\2x-\dfrac{3}{2}=6~~(multiplique~membro~a~membro~por~2)\\\\\\4x-3=12~~(some~3~em~ambos~os~lados~da~igualdade)\\\\\\4x=15~~(divida~ambos~os~lados~da~igualdade~por~4)$
