Four times the sum of a number and 9 is equal to 7?

Answer 1

Eva Adamson

#4x+9=7# or #4(x+9)=7#

It actually depends on how one interprets and comprehends the question, given the lack of punctuation of the question.

Four times the sum of a number and 9 is equal to 7.

This can mean 4 times of a number, then add 9 to get 7.

#4x+9=7#

Four times the sum of a number and 9 is equal to 7.

This can mean 4 times of a number and 9 to get 7.

#4(x+9)=7#

Let ( x ) be the number. The given statement can be represented as:

[ 4(x + 9) = 7 ]

To solve for ( x ), first distribute 4:

[ 4x + 36 = 7 ]

Next, isolate ( x ) by subtracting 36 from both sides:

[ 4x = 7 - 36 ] [ 4x = -29 ]

Finally, divide both sides by 4:

[ x = \frac{-29}{4} ]

So, the number is ( x = \frac{-29}{4} ).

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.
