Answer 2

$\huge\underline\bold\red{Answer}$

Given

x + y = 14. .... equation 1

x - y = 4. ...... equation 2

Now, we will solve it by substitution method;

Let's take equation 1➟

x + y = 14

x = 14 - y

Put the value of x in equation 2➟

x - y = 4

➟ 14 - y - y = 4

➟ 2y = 14 - 4

➟ y = 10/2

➟ y = 5

Now, put the value of y in equation 1 =>

x + y = 14

➟ x + 5 = 14

➟ x = 9

Therefore the value of x = 9 and y = 5

Hope it’s help :)
