Not sure if there was supposed to be a list, but here is one expression that is equivalent. 2.2n+4. Since all I did was add like terms, I can come upon an equivalent expression.
Your answer is going to be B.
First isolate the x. Always remember that the way you do this is the opposite of the what is happening to the number you want to move.
You want to move the -5 from the left side to the right side by doing the opposite and adding it to both sides.
Like: 27x-5=-5+11
27x-5+5=11+5
So 27x=11 Continue to isolate the variable
Answer:
Let the present age of the man be x years.
Age of the man 15 years ago =(x−15) years and
Age of the man 15 years later =(x+15) years
According to the given condition, we have
(x+15)=2(x−15)
⇒x+15=2x−30
⇒x−2x=−30−15
⇒−x=−45 or x=45 years
Hence, the present age of the man is 45 years.
