Question

equação de 1°grau

3+X/5 - x/2 = x-1/2 -3​

Answer 1

$3+\frac{x}{5}-\frac{x}{2}=x-\frac{1}{2}-3$

$\frac{x}{5}-\frac{x}{2}-x=-\frac{1}{2}-3-3$

$\frac{2x}{10}-\frac{5x}{10}-\frac{10x}{10}=-\frac{1}{2}-\frac{6}{2}-\frac{6}{2}$

$-\frac{13x}{10}=-\frac{13}{2}$

$\frac{13x}{10}=\frac{13}{2}$

$2\cdot 13x=13\cdot 10$

$26x=130$

$x=\frac{130}{26}$

$x=5$
