Final answer:
Jada's equation represents the sum of ages where x is the base age, with terms in the equation representing ages that are a certain number of years older or younger than x. The ages when summed up are 3 years older (x+3), 2 years younger (x-2), and the triple of an age 3 years older (3(x+3)) subtracting 1 to get a total age sum of 87.
Step-by-step explanation:
Jada writes this equation for the sum of the ages: (x) + (x+3) + (x−2) + 3(x+3) − 1=87.
The variable x represents a specific but unknown value, which is assumed to be the age of a person, object, or concept that Jada is referring to. Each term in the equation (x), (x+3), (x−2), and 3(x+3) − 1, represents the age of different individuals or the same individual at different times, or various other quantities added together to sum up to 87.
Here is a step-by-step explanation of the terms:
- The first term, x, is a base value.
- The second term, (x+3), indicates an age that is 3 years older than the base value x.
- The third term, (x−2), represents an age that is 2 years younger than x.
- The fourth term, 3(x+3), implies that there are three individuals or items, each of whom is 3 years older than x, contributing to the sum.
- The subtraction of 1 at the end, − 1, possibly adjusts for an overestimate or serves as a correction to the total age.
Adding all these terms equals 87, which is the sum of the ages that Jada is trying to find.
