Answer 1

heya...!!!!

(1)


$\frac{x - 3}{5} + \frac{x - 4}{7} = 6 - \frac{2x - 1}{35} \\ \\ = > \frac{7x - 21 + 5x - 20}{35} + \frac{2x - 1}{35} = 6 \\ \\ = > \frac{12x - 41 + 2x - 1}{35} = 6 \\ \\ = > \frac{14x - 42}{35} = 6 \\ \\ = > 14x = 210 + 42 \\ \\ = > x = \frac{252}{14} \\ \\ = > x = 18$

$\frac{x + 3}{7} - \frac{2x - 5}{3} = \frac{3x - 5}{5} - 25 \\ \\ = > \frac{3x + 9 - 14x + 35}{21} = \frac{3x - 5 - 125}{5} \\ \\ = > \frac{ - 11x + 44}{21} = \frac{3x - 130}{5} \\ \\ = > - 55x + 220 = 63x - 2730 \\ \\ = > 118x = 2950 \\ \\ = > x = \frac{2950}{118} \\ \\ = > x = 25$

$\frac{3y - 2}{7} - \frac{5y - 8}{4} = \frac{1}{14} \\ \\ = > \frac{12y - 8 - 35y + 56}{28} \frac{1}{14} \\ \\ = > \frac{ - 23y + 48}{2} = 1 \\ \\ = > 23y = 46 \\ \\ = > y = \frac{46}{23} \\ \\ = > y = 2$

--(4)


$\frac{x + 3}{2} - \frac{3x + 1}{4} = \frac{2(x - 2)}{3} - 2 \\ \\ = > \frac{4x + 12 - 6x - 2}{8} = \frac{2x - 4 - 6}{3} \\ \\ = > \frac{ - 2x + 10}{8} = \frac{2x - 10}{3} \\ \\ = > - 6x + 30 = 16x - 80 \\ \\ = > 22x = 110 \\ \\ = > x = \frac{110}{22} \\ \\ = > x = 5$
