Question #0db4c

Answer 1

`color(red)(A=35)`

Explanation:

`2^2-1-9*2^2-2+1A=0`

Rearranging the equation by combining the like terms :
`(2^2-9*2^2)-1-2+1A=0`
`2^2(1-9)-(1+2)+1A = 0`

`4*(-8)-3+1A = 0 color(white)(aaa)`writing `2^2 ascolor(white)(a)4`
`-32-3+A=0` as `**1A=A**`

`A=32+3=35color(white)(aaa)` taking constant terms to R H S.
