Question

The solution of the equations x + y = 14 and x – y =4 is
(a) x = 9 and y = 5
(b) x = 5 and y = 9
(c)x = 7 and y = 7
(d) x = 10 and y = 4

Answer 1

Answer:

Answer is a) x =9 and y =5 bcoz 9+5=14 and 9-5=4

Answer 2

Answer:

Option (a) is correct

Step-by-step explanation:

x + y = 14......[1]

x - y = 4.........[2]

Adding 1 and 2 equation

2x = 18

x = 9

Put x = 9 in [1]

9 + y = 14

y = 14 - 9

y = 5
