STEPS TO FOLLOW (as given):


1. Determine the variable
2. Set up the equation
3. Solve

## 🔹 Problem 1:
> 8 less than 3 times a number is 13. Find the number.

Step 1: Determine the variable


Let the number be x

Step 2: Set up the equation


“3 times a number” → 3x
“8 less than 3 times a number” → 3x - 8
“is 13” → = 13
Equation: 3x - 8 = 13

Step 3: Solve


Add 8 to both sides:
→ 3x = 21
Divide by 3:
x = 7

Answer: The number is 7

## 🔹 Problem 2:
> Amy scores 7 points more than 2 times Jill on their unit test. If Amy scored an 87, what did Jill score?

Step 1: Determine the variable


Let Jill’s score = x

Step 2: Set up the equation


“2 times Jill” → 2x
“7 more than 2 times Jill” → 2x + 7
“Amy scored 87” → = 87
Equation: 2x + 7 = 87

Step 3: Solve


Subtract 7 from both sides:
→ 2x = 80
Divide by 2:
x = 40

Answer: Jill scored 40

## 🔹 Problem 3:
> Ava makes 7 dollars per hour plus a weekly bonus of $10. If her paycheck this week was $80, how many hours did she work?

Step 1: Determine the variable


Let hours worked = h

Step 2: Set up the equation


Pay = (hourly rate × hours) + bonus
→ 7h + 10 = 80
Equation: 7h + 10 = 80

Step 3: Solve


Subtract 10 from both sides:
→ 7h = 70
Divide by 7:
h = 10

Answer: Ava worked 10 hours

## 🔹 Problem 4:
> Emmanuel is 2 times older than Jaime. Their ages add to 54. Find both of their ages.

Step 1: Determine the variable


Let Jaime’s age = x
Then Emmanuel’s age = 2x

Step 2: Set up the equation


Sum of their ages = 54
→ x + 2x = 54
Equation: 3x = 54

Step 3: Solve


Divide by 3:
x = 18

So, Jaime is 18, Emmanuel is 2 × 18 = 36

Answer: Jaime is 18, Emmanuel is 36

## 🔹 Problem 5:
> Giselle paid an accountant $25 per hour to do her taxes plus a $100 one-time fee. Her total bill was $250. How many hours did the accountant work?

Step 1: Determine the variable


Let hours worked = h

Step 2: Set up the equation


Total cost = (hourly rate × hours) + fee
→ 25h + 100 = 250
Equation: 25h + 100 = 250

Step 3: Solve


Subtract 100 from both sides:
→ 25h = 150
Divide by 25:
h = 6

Answer: The accountant worked 6 hours

---

## 🔹 Problem 6:
> 9 more than a number divided by 8 is 10. What is the number?

Step 1: Determine the variable


Let the number = x

Step 2: Set up the equation


“a number divided by 8” → x/8
“9 more than that” → x/8 + 9
“is 10” → = 10
Equation: x/8 + 9 = 10

Step 3: Solve


Subtract 9 from both sides:
→ x/8 = 1
Multiply both sides by 8:
x = 8

Answer: The number is 8

## 📝 Final Answers Summary:

1. 7
2. 40
3. 10 hours
4. Jaime: 18, Emmanuel: 36
5. 6 hours
