7u = 7 x u

7 x u, where you could mean any number...
Ex. 7u=28
Divide each side by 7 to isolate the variable
u=4

Right, in algebra you have the Co-efficient which in this case is seven, and the variable, which in this case is u. being a variable u can have any numeric value whatsoever, from zero to infinity, and can be a minus number too, again from zero to infinity, although minus zero is just zero all the same.
Let's assume that in this case u=3. Ergo 7u = 21 (7x3).

means 7 x u
letters in math simply mean the number is not known
but in some cases it is 1.

7 multiplied by whatever u is.

if you add 7u to 7p you get 7up

it means 7 'multiplied by' u, where u could be anything.
