**Number Line Prime Class 6 Solutions Chapter 11 Linear Equations**

Welcome to NCTB Solutions. Here with this post we are going to help 6th class students for the Solutions of Number Line Prime Class 6 Math Book, Chapter 11, Linear Equations. Here students can easily find step by step solutions of all the problems for Linear Equations, Exercise 11A and 11B Also here our mathematics teacher’s are solved all the problems with easily understandable methods with proper guidance so that all the students can understand easily. Here in this post students will get chapter 11 solutions. Here in this post all the solutions are based on latest Syllabus.

**Linear Equations Exercise 11A Solution :**

**Question no – (1) **

**Solution :**

**(a)** Not liner equation.

**(b)** Liner equation.

**(c)** Not liner equation.

**(d)** Liner equation.

**Question no – (2) **

**Solution :**

**(a) 4x – 7 = 9**

If x = 1 then 4 × 1 = 7 ≠ 9

If x = 3 then 4 × 3 – 7 ≠ 9

If x = 4 then 4 × 4 – 7 = 9

So, x = 4

**(b) 8y = 48**

If y = 1 then 8 × 1 ≠ 48

Y = 3 then 8 × 3 ≠ 48

Y = 6 then 8 × 6 = 48

So, Y = 48

**(c) 2m/7 = 2**

If = 1 then 2 × 1/7 ≠ 2

If m = 2 then 2 × 2/7 ≠ 2

If m = 5 then 2 × 5/7 ≠ 2

If m = 7 then 2 × 7/7 ≠ 2

So, x = 7

**(d) 2x – 5 = 5**

If x = 1 then 2 × 1 – 5 ≠ 5

X = 2 then 2 × 2 – 5 ≠ 5

X = 4 then 2 × 5 – 5 ≠ 5

So, x = 5

**Question no – (3) **

**Solution :**

**(a)** x – 7 = 2

**(b)** 8 +2x = 6

**(c)** 6 – x = 3

**(d)** x/2 – 14 7

**(e)** 2 + 4x = 26

**(f)** 8 – x = 15

**(g)** 6 + 4x = 18

If length = x

Breath = (x + 3)

= [x + (x +3)] = 18

**(h)** 37 + x = 46

**Question no – (4)**

**Solution :**

**(a)** Sum of form times of a number and 5 is nine.

**(b)** Some of twice number and one is 5

**(c)** Subtraction of 7 from +2times of a number is 5.

**(d)** Multiplication of 3 and Sum of Y and 1 is 12.

**Question no – (5) **

**Solution :**

Equation |
Value of variable |
Equation Satisfied Yes/No |

(a) 4a = 20 | 5 × 4 = 20 | Yes |

(b) 2x + 5 = 11 | 2 × 3 + 5 = 6 + 5 = 11 | Yes |

(c) 9m – 1 = 8 | 9 × 9 – 1 = 81 – 1 ≠ 80 | No |

(d) 14 + b/2 = 16 | 14 + 2/2 = 14 + 1 ≠ 2 | No |

**Linear Equations Exercise 11B Solution :**

**Question no – (1) **

**Solution :**

**(a) x + 6 = 10**

=> x = 10 – 6

**∵** x = 4

**(b) 5 = a + 2**

=> a + 2 = 5

=> a = 5 – 2

**∴** a = 3

**(c) m – 12 = 3**

=> m = 3 + 12

=> m = 15

**(d) – 7 = x + 4**

=> x + 4 = – 7

=> x = – 7 – 4

**∵** x = – 11

**(e) 4 + k – 7 = 2**

=> k = 2 + 7 – 4

=> k = 9 – 4

**∴** k = 5

**(f) 3a = 6**

=> a = 6/3

**∵** a = 2

**(g) a + 6/2 = 3**

=> a + 6 = 3 × 2

=> a + 6 = 6

**∵** a = 6 – 6

a = 0

**(h) – 4 = x – 1/3**

=> x – 1/3 = – 4

=> x – 1 = – 12

=> x = – 12 + 1

**∴** x = – 11

**(i) 2x = 4/9**

=> x = 4/9 × 2

**∵** x = 2/9

**(j) 3x/2 = 1/8**

=> x (3 × 8) = – 1 × 2

x = – 1 × 2/3 × 8

= – 1/12

**Question no – (2)**

**Solution :**

**(a)** Let the number be = b

So, 9b + 7 = 43

=> 9b = 43 – 7

=> 9b = 36

=> b = 36/9

**∵** b = 4

**(b)** So, karishma’s age

= 11 – 5

= 6 years

**(c)** Let the other number = x

So, x + 12 = 84

=> x = 84 – 12

**∵** x = 72

The other number = 72.
