Question

Find y if (x , 4) = (-7 , x + y)​

Answer 1

Answer:

The value of x is 8 and value of y is 7.

Step-by-step explanation:

Given : (x-4,7) = (4,7)

To find : The value of x and y ?

Solution :

We compare the coordinate to get the value of x and y as the y-coordinate is same.

The coordinates are in form (x,y).

Compare x-coordinate,

x-4=4x−4=4

x=4+4x=4+4

x=8x=8

The y-coordinate is y=7.

Therefore, the value of x is 8 and value of y is 7.
