Question

please tell please

fir branlist​

Answer 1

a-(a-1) /2 = 1-(a-2) /3

(2a-a-1) /2 =(3-a-2) /3

3(2a-a-1) = 2(3-a-2)

6a-3a-3= 6-2a-4

3a-3=2-2a

3a-2a=3+2

so, a =5

Hope I have helped u

Answer 2

$\huge\bf\red{Solution}$

$a - (\frac{a - 1}{2} ) = 1 - \frac{(a - 2)}{3} \\ \\ \frac{2a - a - 1}{2} = \frac{3 - a - 2}{3} \\ \\ \frac{a - 1}{2} = \frac{1 - a}{3} \\ \\ 3(a - 1) = 2(1 - a) \\ \\ 3a - 3 = 2 - 2a \\ \\ 5a = 5 \\ \\ a = 1$

I hope it is the answer Pls make me as brainliest and pls thank my answer ❤
