Answer 2

ANSWER:-

Given:

$\frac{3}{7} (7 m - 1) - \frac{(2m - 1 - m}{2} = \frac{m + 3}{2}$

Solution:

$\frac{3}{7} (7m - 1) - \frac{(2m - 1 - m)}{2} = \frac{m + 3}{2} \\ \\ = > \frac{21m - 3}{7} - \frac{</u><u>(</u><u>m - 1</u><u>)</u><u>}{2} = \frac{m + 3}{2} \\ \\ = > \frac{42m - 6 - 7m </u><u>+</u><u> 7}{14} = \frac{m + 3}{2} \\ \\ = > \frac{35m </u><u>+</u><u>1</u><u>}{14} = \frac{m + 3}{2} \\ \\ = > 70m </u><u>+</u><u>2</u><u> = 14m + 42 \: \: \: \: \: </u><u>[</u><u>cross</u><u> \: multiplication</u><u>]</u><u> \\ \\ = > 70m - 14m = 42 </u><u>-</u><u>2</u><u> \\ \\ = > 56m = </u><u>4</u><u>0</u><u>\\ \\ = > m = \frac{</u><u>4</u><u>0</u><u>}{56} \\ \\ = > m = \frac{</u><u>5</u><u>}{</u><u>7</u><u>}$

Hope it helps ☺️
