Question

The solution of the equation x+y=14and x-y=4​

Answer 1

Answer:

Hey,

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 this helps....:)

HOPE IT IS HELPFUL.

Answer 2

The solution of the equation x+y=14and x-y=4

add both equation.

2x=18

x=9

now, put value of x in above any equation

9+y=14

y=5

so, x=9,y=5
