Question

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

Answer 1

d) x=25

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
