Answer:
Aaron’s present age = x - 5 = 6 - 5 = 1
Step-by-step explanation:
Let Ron’s present age be x.
Then Aaron’s present age = x - 5
After 4 years Ron’s age = x + 4, Aaron’s age x - 5 + 4.
According to the question;
Ron will be twice as old as Aaron.
Therefore, x + 4 = 2(x - 5 + 4)
⇒ x + 4 = 2(x - 1)
⇒ x + 4 = 2x - 2
⇒ x + 4 = 2x - 2
⇒ x - 2x = -2 - 4
⇒ -x = -6
⇒ x = 6
Therefore, Aaron’s present age = x - 5 = 6 - 5 = 1
Hope this answer helps you :)
Have a great day

Answer:
-x² - 9 is your simplified form
Step-by-step explanation:
Combine terms with the same amount of variables.
(2x² - 5) - (3x² + 4)
First, distribute the negative sign to all terms within the second parenthesis
(2x² - 5) - 3x² - 4
Combine like terms
2x² - 3x² = -x²
-5 - 4 = -9
-x² - 9 is your simplified form
