Question

4x-4/5 - x+2/2 - 3/1 = x/10 - 24/5

Qual o resultado?

obs: 4x-4/5 e todas as outras são frações

Answer 1

$\frac{4x-4}{5}- \frac{x+2}{2} - \frac{3}{1}= \frac{x}{10}- \frac{24}{5} \\ \\ \frac{4x-4}{5}- \frac{x+2}{2} - \frac{x}{10} = - \frac{24}{5}+3 \\ \\ \frac{2(4x-4)-5(x+2)-x}{10} = - \frac{9}{5} \\ \\ \frac{8x-8-5x-10-x}{10} = - \frac{9}{5} \\ \\ \frac{2x-18}{10}= - \frac{9}{5} \\ \\ 2x-18=- \frac{90}{5} \\ \\ 2x-18= -18 \\ 2x=-18+18 \\ 2x=0 \\ x=0/2 \\ x=0$
