Question

57x + 600 = x

Qual é o valor de x?

Answer 1

$\large\bm{57x + 600 = x} \\ \large\bm{57x = x - 600} \\ \large\bm{57x - x = - 600} \\\large\bm{56x = - 600} \\ \large\bm{56x \div 56 = - 600 \div 56} \\ \large\bm{x = - 600 \div 56} \\ \\\large\bm{x = - \dfrac{600}{56} } \\\\ \large\bm{x = - \frac{\cancel{600}}{\cancel{56}} } \div 8 \\\\ \bm{\large\boxed{\boxed{  { \large \bm{x = \dfrac{75}{7} }}}}}$

${\large\boxed{\boxed{  { \large \bm{ Bons~Estudos} }}}}$
