Question

1. Which of the following order pair is the solution of x - y = 2 (A) (10, 8) (B) (6, 8) (C) (7, 9) (D) All​

Answer 1

Answer

(A) - 10,8

Checking

LHS=

=x - y

=10 - 8

=2

RHS=

=2

Answer 2

Answer:

(a) (10,8)

Step-by-step explanation:

in (a), x=10 and y=8 so x-y=10-8=2 which satisfies the equation

in (b) x=6 and y=8 so x-y=6-8=-2 which doesn't satisfy the equation

in (c) x=7 and y=9 so x-y=7-9=-2 which doesn't satisfy the equation

so (d) is also incorrect as only one of the options is correct
