Question

If x = a , y = b is the solution of the pair of equations x - y = 4 and x + y = 6 , then value of a and b are respectively​

Answer 1

As x=a and y=b

then

⇒a−b=2...(1)

⇒a+b=4....(2)

Adding eq1 and eq2

⇒2a=6

⇒a=26=3

Substitute the value of a in eq1

⇒3−b=2

⇒−b=2−3

⇒b=1

Hence the value of a=3  and b=1
