solve it please​

Answer 1

Answer:

Thus question answer is a x. = 8 , y.= 2

Answer 2

Step-by-step explanation:

x+y=10---------[1]

x-y=12---------[2]

By substitution method,

x=10-y---------[3]

Putting value of x from eq [3] in eq[2],we get,

(10 - y)-y=12

10-2y=12

-2y=12-10

-2y=2

Y=-1

Putting value of y in eq 3, we get,

x=10 -(-1)

=10+1

x=11.

Thus, value of X=11 &Y=-1.
