Answer 1

Answer:

hi

your answer is

a+1(27) = a-1(18)

27a+27 = 18a-18

27a-18a = -18-27

9a = 45

therefore, a = 45

hope you like it ☺️☺️

Answer 2

Answer:

$\frac{a + 1}{18} = \frac{a - 1}{27} \\ \\ 27(a + 1) = 18(a - 1) \\ 27a + 27 = 18a - 18 \\ 27a - 18a = - 18 - 27 \\ 9a = - 45 \\ a = \frac{ - 45}{9} \\ = - 5$
