Answer:
Step-by-step explanation:
First, turn the word problem into an equation:
n(a number) was divided by 2

followed by this quotient beying multiplied by 4
 *4
*4
the product was added to 9
 *4+9
*4+9
the total sum was 25
 *4+9 = 25
*4+9 = 25
use PEMDAS to solve the equation
subtract 9 on both sides
 *4 = 16
*4 = 16
cancel the 2 and the 4 using factorization
n*2 = 16
divide 2 on both sides
n = 8
