Question

solve this pair of linear equation by subsistution method x+y=14 and x-y=4​

Answer 1

Answer:

Heya.....here is your answer

Step-by-step explanation:

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

Answer 2

Answer:

Step-by-step explanation:

X+Y= 14 ........(i)

X-Y= 4 ..........(ii)

Now, Adding both we get,

X+Y= 14

X-Y= 4

_______

2X= 18

or X= 9

Putting value of X in (i) we get,

9 + Y= 14

or, Y= 14 - 9

or, Y= 5
