Question

What is the sum of six times a number and 25

Answer 1

Call the number 'Q' until we know what it really is.

The number . . . . . Q

6 times the number . . . 6Q

The sum of 6 times Q and 25 . . . ( 6Q + 25 ) .

That's all we can do with it, because we still don't know what number Q really is.

Answer 2

six times a number: 6(x)

The sum of 6(x) and 25: 6x + 25

6x + 25 is your expression.

hope this helps
