X= a number

29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4

CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21

ANSWER: The number is 4.

Hope this helps! :)

erica [24]

Answer:

Contradictrion

Step-by-step explanation:

First write an equation. If the total is 289, then that goes one the right side of the =. Sociology textbooks will be x. If there were 65 less than x, it will be 65-x. Lets set it up:

x + 65 -x =289

Then combine like terms.

65 = 289

There are no values of x that make the equation true. The input is a contradiction.
