Question

8. Find the solution to the equation from the given set of values:
7x - 7=7
(1.2,-2.3)​

Answer 1

Given :  7x - 7y   = 7

To Find :   solution to the equation from the given set of values:

(1 , 2)

(-2 , 3)

(1 , - 2)

(-2, - 3)

Solution:

7x - 7y   = 7

=> x - y  = 1

x = 1

=> 1 - y = 1

=> y = 0

x = -2

=> -2 - y = 1

=> -y = 3

=> y = - 3

(-2, - 3)

(-2, - 3) is solution of given  equation from the given set of values:
