$\frac{x}{2} + 5 = \frac{5x}{3} - 2$
​

Answer 1

A raiz da equação é :

${{\boxed{\boxed{\Large{\boxed{\rm { x=6 \: }}}}}}}$

Montando a equação :

$\dfrac{x}{2} +5=\dfrac{5x}{3} -2\\\\\\3x+30=2\times5x-12\\\\\\3x+30=10x-12\\\\\\3x+30-10x-12\\\\\\-7x+30=-12\\\\\\-7x=-12-30\\\\\\-7x=-42\\\\\\x=\dfrac{-42}{-7} \\\\\\x=6$
