If #x# represents a number, how do you write an expression for a number that is three more than twice the value of #x#?

Answer 1

#3 + 2x" or "2x +3#

The number is #x# .

Write an expression for each phrase first:

"three more than" means 3 is added.

(10 is 3 more than 7 means 7+3 = 10)

"twice the value of" means "multiply by 2", or "double". (twice 6 means 2 x 6,)

The other number we are looking for is: whatever #x# is, doubled, and then 3 is added.
#3 + 2x" or "2x +3#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
