Question

Como se monta essa equação 7x+10=6x+5

Answer 1

$\large\boxed{\begin{array}{l}\underline{\rm 1^a\,forma\,de\,resolver:}\\\rm 7x+10=6x+5\\\rm usando\,o\,princ\acute ipio\,aditivo,vamos\,subtrair\\\rm 10\,dos\,dois\,lados.\\\rm 7x+\diagup\!\!\!\!\!10-\diagup\!\!\!\!\!\!10=6x+5-10\\\rm 7x=6x-5\\\rm novamente\,usando\,o\,princ\acute ipio\,\,aditivo\\\rm vamos\,subtrair\,6x\,dos\,dois\,lados\\\rm 7x-6x=\diagup\!\!\!\!\!\!6x-\diagup\!\!\!\!\!\!\!6x-5\\\rm x=-5\end{array}}$

$\large\boxed{\begin{array}{l}\underline{\sf 2^a\.forma\,de\,resolver:}\\\rm 7x+10=6x+5\\\rm 7x-6x=5-10\\\rm x=-5\end{array}}$
