Question

the solution of the system of linear equations x+y= 14 and x-y= 4 is
x=5,y=9
x= -5,y=9
x= -5, y= -9
x=9,y=5

Answer 1

Answer:

x+y=14-------1

x-y=4------2

solving we get 2x=18

x=9

put the value of x in eq 2

y=9-4=5

Step-by-step explanation:

answer is x=9,y=5

Answer 2

Answer:

x=9, y=5

Step-by-step explanation:

Since, x+y=14 ..(a)

x-y=4 ..(b)

Take (a)+(b),

x+y=14

+ x-y =4

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

2x =18

x =9

Now, Put x=9 in (a)

9+y=14

y=5

Therefore, x=9,y=5
