Ulani has an older siste and a younger sister. Her older sister is one year more than twice Ulani's age. Ulani's younger sister is three years younger than she is. The sum of their ages is 26. Find Ulani''s age

2x + 1 - 3 = 26

How about

x-3 + x + 2x+1 = 26

Let's break down the problem into steps.

1. Let's set up variables for each person's age.
- Let Ulani's age be "x"
- Let Ulani's older sister's age be "2x + 1"
- Let Ulani's younger sister's age be "x - 3"

2. We know that the sum of their ages is 26. Therefore, we can set up an equation:
x + (2x + 1) + (x - 3) = 26

3. Now, let's solve the equation:
Combining like terms, we have:
4x - 2 = 26

Adding 2 to both sides, we have:
4x = 28

Dividing both sides by 4, we have:
x = 7

Therefore, Ulani's age is 7.

To solve for Ulani's age, let's set up equations based on the given information:

Let Ulani's age be represented by x.

1) Ulani's older sister is one year more than twice Ulani's age:
Ulani's older sister's age = 2x + 1

2) Ulani's younger sister is three years younger than she is:
Ulani's younger sister's age = x - 3

3) The sum of their ages is 26:
x + (2x + 1) + (x - 3) = 26

Now, let's solve the equation:

Combine like terms on the left side:
4x - 2 = 26

Add 2 to both sides:
4x = 28

Divide both sides by 4:
x = 7

Therefore, Ulani is 7 years old.
