$10 x$ $10x$

In algebra you can only add like terms.

$7 x + 3 x$ $7x + 3x$ can be written as:

$x + x + x + x + x + x + x + x + x + x$ $x+x+x+x+x+x+x" "+x+x+x$

As they are all terms in $x$ $x$ we can simply ask how many $x$ $x$ s are being added altogether.?

There are seven $x$ $x$ s and another three $x$ $x$ s.

They are all like terms which gives:

$7 x + 3 x = 10 x$ $7x + 3x = 10x$
