Question

solve the following pair of linear equations by the substitution method X + Y =14 , x - y = 4​

Answer 1

Answer:

please mark me as brainliest

Step-by-step explanation:

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....:)

Answer 2

Answer:

X+Y=14

X=14-Y

Step-by-step explanation:

X-Y=4

X=4+Y
