Answer:

x = 2

Step-by-step explanation:

4 x + (negative 4) = negative 2 x + 8

4x + (-4) = - 2x + 8

4x - 4 = - 2x + 8

4x + 2x = 8 + 4

A $\textit{palindrome}$ is a positive integer which reads the same forward and backward, like $12321$ or $4884$. How many $4$-di

Norma-Jean [14]

There are 90 4-digit palindromes

<h3>What are palindromes?</h3>

Palindromes are numbers whose reverse is the same as the original number

<h3>How to determine the count of 4-digit palindromes</h3>

Since the digit is 4, then

The first digit of the palindrome can be any of 1 to 9 (i.e. 9 digits)
The second digit can be any of 0 - 9 (i.e. 10 digits)
The third digit must be the second digit (i.e. 1 digit)
The last digit must be the first digit (i.e. 1 digit)

So, the total number of digits is:

$n =9 * 10 * 1 * 1$

Evaluate the product

$n =90$

Hence, there are 90 4-digit palindromes.
