median belfry
#

it would be the same So the bottom part is x+ 6

#

let me screenshot and label them

prime niche
#

ohhhhhh the value is x

#

i thought it was a missing value

#

my bad

#

oh i do get how to solve it nvm

#

x = 5

#

or x = -9 but u can't get a negative length

#

so its x = 5 which links to the top q

#

makes sense but thank u
