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:
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
