Question

12. x + y = 14
x - y = 4​

Answer 1

Answer:

x=9 and y=5

Step-by-step explanation:

Add both the equations

hence 2x=18

x=9

subtract both the equations

2y=10

y=5

hope this helps:)

Answer 2

Step-by-step explanation:

From equation second

x=4+y

now

x+y=14

4+y+y=14

4+2y=14

2y=ten

y=ten/2

y=5

x=4+y

x=4+5

x=9.
