Question

If x + y = 10 and x - y = 12, then

​

Answer 1

Answer:x=11/2

Step-by-step explanation:

x+y=10--------------------eq1

x-y=1-----------------------eq2

add eq1 and eq2

2x=11

x=11/2-----------------eq3

substitute eq3 in eq 1 or eq2

Answer 2

Answer:

= x + y =10

= x - y = 12

-----------------

=2x =22

=x =22/2

=x=11

Putting the value of x in any one equation

Here = x + y=10

=11 +y=10

= y =10-11

=y=-1
