It probably means they want you to solve for a.
I can't think of anything else.
I've seen other, more involved problems, such as
a(b+3) = d(b-7) ; b
where they wanted to solve for b.
10+a= 25; a
is the ";" a line of symmetery?

i meant symmetry TvT
I know that a=15 but idk if the ; is a line of symmetry or not
there's no graph involved! it's just a point on the number line.
How would you even come up with a line of symmetry?
