alleryStart learning →A number x is reduced by 5; the result is then doubled to give 16. Which equation models this?
Ax−10=16
B2(x+5)=16
C2(x−5)=16
D2x−5=16
Answer & Solution
Correct answer: C. 2(x−5)=16
The first operation produces x−5. Doubling that entire result produces 2(x−5), which equals 16.
