Question

if x=a and y = b us the solution of the equations x-y = 2 and x + y = 4 find the value of a and b​

Answer 1

Step-by-step explanation:

As x=a and y=bthen

⇒a−b=2............(1)

⇒a+b=4............(2)

Adding eq1 and eq2

⇒2a=6

⇒a=

2

6

=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

Answer 2

Refer the above Attachment....

Value of a = 3

Value of b = 1
