What is the solution to this equation?

X - 16 = 9

O A. x=-7

O B. x = 7

O C. x = - 25

O D. x = 25

d) x=25

Step-by-step explanation:

x-16=9

add 16 to both sides canceling out - 16 and adding 9 and 16, making it positive 25

after moving 16 to the other side of the =, and adding it to 9 it should look like:

x=25

therefore making the answer x=25
