Question

(i) x + y = 14
x=y=4​

Answer 1

There is typing mistake in question

x+y=14

x=14-y

x-y=4

now putting x=14-y we get

14-y-y=4

=-2y=4-14

=y=10/2

y=5

x=14-5=9

the value of x=9 , y=5

Answer 2

(i) Given,

x + y = 14 and x – y = 4 are the two equations.

From 1st equation, we get,

x = 14 – y

Now, substitute the value of x in second equation to get,

(14 – y) – y = 4

14 – 2y = 4

2y = 10

Or y = 5

By the value of y, we can now find the exact value of x;

∵ x = 14 – y

∴ x = 14 – 5

Or x = 9

Hence, x = 9 and y = 5.
