Introduction to Mathematics

Mathematics is a subject that deals with numbers, quantities, and shapes. It is a vital part of our daily lives, and we use it to solve problems, make calculations, and understand the world around us. In this article, we will be discussing some math problems from the S. Chand Class 9 book and providing answers to them.

Problem 1: Find the value of x in the equation 2x + 5 = 11

To solve this equation, we need to isolate the variable x. We can do this by subtracting 5 from both sides of the equation and then dividing both sides by 2.

2x + 5 = 11

Subtracting 5 from both sides:

2x = 11 - 5 2x = 6

Dividing both sides by 2:

x = 6/2 x = 3

Therefore, the value of x is 3.

Problem 2: Find the value of y in the equation y - 3 = 7

To solve this equation, we need to isolate the variable y. We can do this by adding 3 to both sides of the equation.

y - 3 = 7

Adding 3 to both sides:

y = 7 + 3 y = 10

Therefore, the value of y is 10.

Problem 3: Find the value of z in the equation z/4 = 9

To solve this equation, we need to isolate the variable z. We can do this by multiplying both sides of the equation by 4.

z/4 = 9

Multiplying both sides by 4:

z = 9 x 4 z = 36

Therefore, the value of z is 36.

Problem 4: Find the value of a in the equation a + 2 = 9

To solve this equation, we need to isolate the variable a. We can do this by subtracting 2 from both sides of the equation.

a + 2 = 9

Subtracting 2 from both sides:

a = 9 - 2 a = 7

Therefore, the value of a is 7.

Problem 5: Find the value of b in the equation b - 2 = 5

To solve this equation, we need to isolate the variable b. We can do this by adding 2 to both sides of the equation.

b - 2 = 5

Adding 2 to both sides:

b = 5 + 2 b = 7

Therefore, the value of b is 7.

Problem 6: Find the value of c in the equation c/3 = 6

To solve this equation, we need to isolate the variable c. We can do this by multiplying both sides of the equation by 3.

c/3 = 6

Multiplying both sides by 3:

c = 6 x 3 c = 18

Therefore, the value of c is 18.

Problem 7: Find the value of d in the equation d + 4 = 11

To solve this equation, we need to isolate the variable d. We can do this by subtracting 4 from both sides of the equation.

d + 4 = 11

Subtracting 4 from both sides:

d = 11 - 4 d = 7

, the value of d is 7.

Problem 8: Find the value of e in the equation e - 4 = 3

To solve this equation, we need to isolate the variable e. We can do this by adding 4 to both sides of the equation.

e - 4 = 3

Adding 4 to both sides:

e = 3 + 4 e = 7

Therefore, the value of e is 7.

Problem 9: Find the value of f in the equation f/2 = 8

To solve this equation, we need to isolate the variable f. We can do this by multiplying both sides of the equation by 2.

f/2 = 8

Multiplying both sides by 2:

f = 8 x 2 f = 16

Therefore, the value of f is 16.

Problem 10: Find the value of g in the equation g + 3 = 10

To solve this equation, we need to isolate the variable g. We can do this by subtracting 3 from both sides of the equation.

g + 3 = 10

Subtracting 3 from both sides:

g = 10 - 3 g = 7

Therefore, the value of g is 7.
