Answer 1

Step-by-step explanation:

Given;

X= a

Y= 6.

ATQ;

X- Y= 2

= a- 6= 2

= a = 2+6=8.

and, X+ Y= 4

= X+ 6 = 4

= X= 4- 6=-2.

here, is Ur ans..mates thnx.. follow..mark as brainlist..

Answer 2

$\huge\underline\mathrm{Question:-}$

• To find value of a & y

$\huge\underline\mathrm{</strong><strong>Answer</strong><strong>:-}$

x = a ; y = 6

Placing values .. According 2 conditions.

★ 1st Condition -

x - y = 2

→ a - 6 = 2

→ a = 2 + 6

→ a = 8

★ 2nd Condition -

x + y = 4

→ x + 6 = 4

→ x = 4 - 6

→ x = - 2

★ Value of a = 8

★ Value of x = -2
