Question

x+y=14 and x-y =4 by multiplication method ​

Answer 1

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
