Let’s solve each problem one by one. We’re writing
one-step equations based on word problems — that means we’ll write an equation with just one operation (like +, –, ×, or ÷) to find the unknown value.

Problem 1:
Penny saved $58.
Freida saved *s* dollars.
Penny saved $6 more than Freida.
That means:
Freida’s amount + $6 = Penny’s amount
→ s + 6 = 58
✔ Equation:
s + 6 = 58

Problem 2:
Total new houses = 105
Brick houses = 45
Non-brick houses = *n*
So:
Brick houses + Non-brick houses = Total houses
→ 45 + n = 105
✔ Equation:
45 + n = 105
---
Problem 3:
Total pens sold = 245
Red pens = 63
Blue pens = *b*
So:
Red pens + Blue pens = Total pens
→ 63 + b = 245
✔ Equation:
63 + b = 245
---
Problem 4:
Lydia has 4 quarters and *x* dimes.
Total coins = 20
So:
Quarters + Dimes = Total coins
→ 4 + x = 20
✔ Equation:
4 + x = 20
---
Final Answer:
1. s + 6 = 58
2. 45 + n = 105
3. 63 + b = 245
4. 4 + x = 20
