Answer 1

Hey buddy, hope you find this solution helpful! If so, please do mark it as the brainliest answer!

Answer:

  a = 3 ; b = 1

Step-by-step explanation:

  x - y = 2 → [Eq. 1]

  x + y = 4 → [Eq. 2]

Now, by subtracting [Eq. 1] from [Eq. 2], we get

  2y = 2

⇒ y = b = 1

Substituting y = 1 in [Eq. 2],

   x + 1 = 4

⇒ x = a = 3

∴ the values of a and b are 3 and 1 respectively.

Answer 2

u just hv to solve it simultaneously to obtain the values of x and y hence find a & b.... wait let me show u....
