How to Solve Algebra Problems for Class 7

In this section, many key points will help you solve algebraic problems for Class 7 easily. 

  1. Read the Problem Carefully

When you have been given a problem to solve, you should read the question very carefully. This will help you understand what you need to solve.

  1. Identify the Variable

A variable is the basic term that is unknown. The main purpose of any algebra question is to find the unknown value. Hence, identify the variable carefully.

  1. Apply the Correct Operation

After identifying the variable, the next step is to choose the appropriate operation. One thing to keep in mind is that if you choose the wrong operation, then the answer will be wrong.

  1. Solve

Then solve the question step by step according to the BODMAS rule.

  1. Check the Answer

The final step is to check whether your answer is correct.

15 Solved Examples of Algebra for Class 7

Q1. Simplify 5x + 3x − 6

Solution:

= 5x + 3x – 6

= 8x – 6

Q2. Simplify 4(a + 4)

Solution:

= 4(a + 4)

= 4a + 16

Q3. Find the value of 3x + 15 when x=3.

Solution:

= 3x + 15

= 3(3) + 15

= 9 + 15

= 24

Q4. Find 4a – 5b if a = 2 and b = 3.

Solution:

= 4a – 5b 

= 4(2) – 5(3)

= 8 – 15

= -7

Q5. Solve x + 8 = 12. 

Solution:

x + 8 = 12

x + 8 – 8 = 12 – 8

x = 4

Q6. Solve 6y = 48.

Solution:

6y = 48

y = 48 / 6

y = 8

Q7. 2x + 5 = 19.

Solution:

2x + 5 = 19

2x + 5 – 5 = 19 – 5

2x = 14

x = 14 / 2

x = 7

Q8. Solve 3m − 6 = 21

Solution:

3m – 6 = 21

3m – 6 + 6 = 21 + 6

3m = 27

m = 27 / 3

m = 9

Q9. Solve 3(x + 3) = 16

Solution:

3(x + 3) = 16

3x + 9 = 16

3x = 16 – 9

3x = 7

x = 7 / 3

Q10. Simplify 2(4x + 14) − 5x

Solution:

= 2(4x + 14) – 5x

= 8x + 28 – 5x

= 3x + 28

Q11. Solve x / 4 = 7

Solution:

x / 4 = 7

x = 7 × 4

x = 28

Solution:

= 33 + 5

= 27 + 5 

= 32

Q13. Expand x(2x + 5).

Solution:

= x(2x + 5)

= 2x2 + 5x

Q14. Solve 4(x − 3) = 20

Solution:

4(x − 3) = 20

4x – 12 = 20

4x – 12 + 12 = 20 + 12

4x = 32

x = 32 / 4

x = 8

Q15. Solve 5x + 2( x + 2) = 4x

Solution:

5x + 2( x + 2) = 4x

5x + 2x + 4 = 4x

7x + 4 = 4x

7x – 4x = -4

3x = -4

x = -4/3

FAQs

Q1. Why is algebra taught so early, like in class 7?
Because it’s the base for every student. Without algebra, higher math would feel impossible.

Q2. How many problems should I practice daily?

No fixed rule. But honestly, 3–5 carefully solved problems each day beats solving 20 in one sitting and forgetting them by tomorrow. 

Q3. Are word problems really worth the effort?

Yes, because life is basically a word problem. Money, time, distance, sharing, all of it. They train you to connect numbers with reality. 

Q4. Do I need to memorize formulas?

Some, yes. But don’t force it. If you understand why a formula works, it sticks naturally. Memorization becomes way easier when it makes sense.
