Question

b)Find the values of x and y, if two ordered pairs (x – 3, – 6) and (4, x + y) are equal

Answer 1

(x -3, -6) = (4, x + y)

⇒ x - 3 = 4

⇒ -6 = x + y

Find x :

x - 3 = 4

x = 4 + 3

x = 7  

Find y :  

-6 = x + y

We  had found x = 7 earlier

-6 = 7 + y

y = -6 - 7

y = -13

Answer: x = 7 and y = -13

Answer 2

Answer:

Value of X=7 and Value of Y=-13

Step-by-step explanation:

First of all solve.

LHS to LHS and then RHS to RHS.

In LHS.

x-3 and 4 and in RHS -6 and X+Y.

In LHS,

x-3=4.

x=4+3.

x=7.

Now, in RHS,

-6=X+Y.

We know the value of X, only just we have to put the value of X.

-6=7+Y.

-6-7=Y.

-13=Y.

{HENCE, the value of X=7 and the value of Y=-13
