$5 (x - 3)$ $5(x-3)$ .

"Five times" means $5(...),$ "the sum of a number, say $x$ , and $-3$ ", means"{(x+(-3)}=(x-3)#.

Taking all these together, the reqd. Algebraic Expression turns out to be $5(x-3)$ .

$5(x-3)$

The word "SUM" means the answer to an "ADDITION".

"SUM" is always used with the word "AND" to indicate which numbers are being added.

The SUM of a number AND -3 is written as: $(x+(-3)) , or (x-3)$

(where we have chosen the number to be $x$ .)

But we want FIVE of those sums; this means:

$5(x-3)$
