Question -10

matrices ml class 10 8.2 question 10

Answer-10

2\begin{bmatrix} 3 & 4 \\ 5 & x \end{bmatrix}+\begin{bmatrix} 1 & y \\ 0 & 1 \end{bmatrix}=\begin{bmatrix} 7 & 0 \\ 10 & 5 \end{bmatrix}

\begin{bmatrix} 6 & 8 \\ 10 & 2x \end{bmatrix}+\begin{bmatrix} 1 & y \\ 0 & 1 \end{bmatrix}=\begin{bmatrix} 7 & 0 \\ 10 & 5 \end{bmatrix}

Matrices Solutions of Chapter-8 ML Aggarwal for ICSE Maths Class 10th Exercise-8.2 Answer-10

On comparing the corresponding elements, we have

8 + y = 0

Then, y = -8

And, 2x + 1 = 5

2x = 5 – 1 = 4

x = 4/2 = 2

Therefore, x = 2 and y = -8

Question -11

matrices ml class 10 8.2 question 11

Answer -11

2\begin{bmatrix} 3 & 4 \\ 5 & x \end{bmatrix}+\begin{bmatrix} 1 & y \\ 0 & 1 \end{bmatrix}=\begin{bmatrix} z & 0 \\ 10 & 5 \end{bmatrix}

Matrices Solutions of Chapter-8 ML Aggarwal for ICSE Maths Class 10th Exercise-8.2 Answer-11

On comparing the corresponding terms,

2x + 1 = 5

2x = 5 -1 = 4

x = 4/2 = 2

And,

8 + y = 0

y = -8

And, z = 7

Therefore, x = 2, y = -8 and z = 7.

Question -12 find the value of x and y if 

matrices ml class 10 8.2 question 12

Answer-12

matrices ml class 10 8.2 question 12
Matrices Solutions of Chapter-8 ML Aggarwal for ICSE Maths Class 10th Exercise-8.2 Answer-12

on comparing the corresponding terms,

4 – 4x = -8

4 + 8 = 4x

12 = 4x

x = 12/4

x = 3

And, y + 5 = 2

y = 2 – 5 =

y = -3

Hence, x = 3 and y = -3

Question -13 Find the value of a, b and c if 

 matrices ml class 10 8.2 question 13
Answer -13

matrices ml class 10 8.2 question 13
Matrices Solutions of Chapter-8 ML Aggarwal for ICSE Maths Class 10th Exercise-8.2 Answer-13

comparing the corresponding terms,

a + 1 = 5 ⇒ a = 4

b + 2 = 0 ⇒ b = -2

-c = 3 ⇒ c = -3

Hence, the value of a, b and c are 4, -2 and -3 respectively.

Question -14 If 

 matrices ml class 10 8.2 question 14 

and 5A + 2B = C, find the values of a, b, c

Answer-14

matrices ml class 10 8.2 question 14
and 5A + 2B = C
Matrices Solutions of Chapter-8 ML Aggarwal for ICSE Maths Class 10th Exercise-8.2 Answer-14

On comparing the corresponding terms,

5a + 6 = 9

5a = 9 – 6

5a = 3

a = 3/5

And,

25 + 2b = -11

2b = -11 – 25

2b = -36

b = -36/2

b = -18

And, c = 6

Hence, the value of a, b and c are 3/5, -18 and 6 respectively.
