Haven Vega · Answer 1

It would be 5+x, 5 being the age difference

Adelyn Stewart · Answer 2

The equation is, x = x + 5,

And, the equation has no solution.

Step-by-step explanation:

Here, x represents Jenna's age in years,

Given,

Jessica is 5 years older than her sister Jenna,

⇒ The age of Jessica = (x + 5) years,

Now, the age of jenna after 5 years = x + 5,

And, the age of Jessica in 5 year ago = (x+5) - 5 = x

According to the question,

x = x + 5

Which is the required equation that represents the situation

0 = 5 (False)

Thus, the equation has no solution.
