Question

x+y=14
x-y=4
solve of subsition method​

Answer 1

Step-by-step explanation:

x+y=14 (1)

x-y= 4 (2)

from equation (1)

x+y=14

x= 14-y

put the value of x in equation (2)

x-y=4

(14-y) -y=4

14+2y=4

2y= 4-14

2y= -10

y= -10/2

y=-5

put the value of y in equation (1)

x+y=14

x+-5 =14

x= 14+5

x= 19

Answer 2

Answer:

x= 9, y = 5

Step-by-step explanation:

x+y= 14

x=14 - y ( take it as 1)

x-y = 4

( put 1)

14 - y - y - 4 = 0

10 - 2y = 0

- 2y = - 10

y = 10\2

y = 5

Now Put y= 5 in 1

x = 14 - 5 = 9
