Answer:

Explanation:

a. (x +y , 1) = (3 , x -y)

compare the corresponding elements

x + y = 3

x = 3 -y              equation(i)

substitute the value of x in equation

1 = x -y

1 = 3 - y -y

1 = 3 - y - y

1 - 3 = -2y

-2 = -2y

-2/-2 = y

1 = y

again substitute the value of x in equation (i)

x = 3 - y

x = 3 - 1

x = 2

b. (x + 5 , 3) = (2 , y - x)

compare the corresponding elements

x + 5 = 2

x = 2 - 5

x = -3

substitute the value of x in equation

3 = y - x

3 = y - (-3)

3 = y + 3

3 - 3 = y

0 = y

c. (y - 2 , x + 1) = (x - 1 , y + 2)

compare the corresponding elements

y - 2 = x - 1

y = x - 1 + 2

y = x +1                equation (i)

substitute the value of y in equation

x + 1 = y + 2

x + 1 = x + 1 + 2

x + 1 = x + 3

x = x + 3 -1

x = x +2

substitute the value of x in equation (i)

y = x + 1

y = x + 2 + 1

y = x + 3
