#2x+6#

Explanation:

Multiply the contents of the brackets by 2

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Compare to the word phrase of "two apples"

We do not say "two of apples"

Nor do we say "two times apples"

So #2(x+3)# is saying the same thing. In that we have two of #(x+2)#.

Write as#" "x+3#
#" "underline(color(white)(.)x+3)" "larr" add"#
#" "2x+6#
