## 🔹 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
