Question

Qual o valor do x , como fazer a conta

Answer 1

$(3,5 \: . \: x) \cancel{- x} - 250 = \cancel{- x} + 250\\ 3,5x - 250 = 250 \\ 3,5x = 250 + 250 \\ 3,5x = 500 \\ x = 500 \div 3,5 \\ x = 500 \div \frac{35 {}^{ \div 5} }{10 {}^{ \div 5} } \\ x = 500 \div \frac{7}{2} \\ x = 500 \times \frac{2}{7} \\ x = \frac{500 \times 2}{7} \\ \boxed{x = \frac{1000}{7} }$
