Answer 2

Answer:

c) Rational number

Step-by-step explanation:

first, find the value of x.

$8x - 13 = 25 + 16x \\ → - 13 = 25 + 16x - 8x \\ → - 25 - 13 = 16x - 8x \\ → - 38 = 8x \\ →x = \frac{ - 38}{8} \\ →x = \frac{ - 19}{4}$

As the value of the numerator is an integer, it is a rational number, because fractions do not contain integers.
