$x = \frac{10}{7}$ $x=10/7$

Explanation:

$x - 5 + 8 x - 2 x + 3 = 8$ $x-5+8x-2x+3=8$
$7 x - 2 = 8$ $7x-2=8$
$7 x = 10$ $7x=10$
$x = \frac{10}{7}$ $x=10/7$

verifying,

$\frac{10}{7} - 5 + 8 (\frac{10}{7}) - 2 (\frac{10}{7}) + 3$ $10/7-5+8(10/7)-2(10/7)+3$
$\frac{10}{7} (1 + 8 - 2) + 3 - 5$ $10/7(1+8-2)+3-5$
$\frac{10}{7} (7) - 2$ $10/7(7) -2$
$10 - 2$ $10-2$
$8$ $8$
RHS

hence verified.!
