Step-by-step explanation:

19.

$\frac{x-1}{2} - \frac{x-3}{5} - \frac{x-7}{10} + \frac{x-2}{5}$
$\frac{5(x-1)-2(x-3)-(x-7)+2(x-2)}{10}$
$\frac{5x-5-2x+6-x+7+2x-4}{10}$
$\frac{4x+4}{10}$
$\frac{2x+2}{5}$

20.

$\frac{2x+3}{2x} + \frac{x+3}{4x} - \frac{18x+6}{8x^{2} }$
$\frac{4x(2x+3)+2x(x+3)-(18x+6)}{8x^{2} }$
$\frac{8x^{2} +12x+2x^{2} +6x-18x-6}{8x^{2} }$
$\frac{10x^{2}-6}{8x^{2} }$
$\frac{5x^{2}-3}{4x^{2} }$
