Three notebooks cost the same amount each. Add one $2 pen and the total is $14. What does one notebook cost?

Let n be the price of one notebook. Then 3n + 2 = 14. Subtract 2: 3n = 12. Divide by 3: n = 4.

Each notebook costs $4. Check: $4 + $4 + $4 + $2 = $14.

Two points: (1, 2) and (3, 6). What is the slope?

Change in y: 6 − 2 = 4. Change in x: 3 − 1 = 2. Slope = 4/2 = 2.

The y-value rises by 2 for each 1-unit increase in x along this line. Keep the order of the points consistent in the numerator and denominator.

For algebra homework, try asking “Why is that step allowed?”

For example, in x + 7 = 12, subtracting 7 from both sides keeps the equation balanced. It gives x = 5.

If your child cannot explain a step yet, work through a simpler example together. Understanding the reason is a useful goal alongside getting the answer.

An equation is a balance. Whatever operation you apply to one side, apply to the other.

3x + 5 = 20 → 3x = 15 → x = 5.

Check: 3(5) + 5 = 20. Checking helps you catch a slip before handing in your work.

Try 4x + 2 = 18. Answer: x = 4.

A student jumps from 3x + 5 = 20 to x = 20 ÷ 3. What is missing?

Subtract 5 from BOTH sides first: 3x = 15. Then divide both sides by 3: x = 5.

Check it in the original equation: 3(5) + 5 = 20.

Your turn: solve 2x + 4 = 14. Answer: x = 5.
