Pls solve this question in detail and step by step....i faced little issues at ending of this question (coordinate geometry class 10)

Question

Answer 1

Following is the simplest way to tackle such questions:

Given: P(3, 2) and Q(x, -1). Also, the distance between P and Q= 5 units.

To find: The value of 'X'

Solution: We know by mid-point formula in co-ordinate geometry that:

For X, we have X2  + X1 / 2 and for Y, we have: _{Y2 + Y1  /2}

From X we have : X2 + X1/ 2 i.e. 

=> 3 + x/2 = 5

=> 3+ x= 10 

=> x= 7 

Answer  X= 7
