Answer 1

5(4a+8+5a-15)=5(3a-5)

45a-35=15a-25

30a=10

a=1/3

Answer 2

Answer:

$\frac{a + 2}{4} + \frac{a - 3}{5} = \frac{3a - 5}{8}$

$\frac{5(a + 2) + 4(a - 3)}{20} = \frac{3a - 5}{8}$

$\frac{5a + 10 + 4a - 12}{20} = \frac{3a - 5}{8}$

$\frac{9a - 2}{20} = \frac{3a - 5}{8}$

$8(9a - 2) = 20(3a - 5)$

$72a - 16 = 60a - 100$

$72a - 60a = - 100 + 16$

$12a = - 84$

$a = \frac{ - 84}{12}$

$a = - 7$

Hope this answer helps you ☺️
