Question

find the points of intersection for this pair of linear equation x+y=14,x-y=4​

Answer 1

Answer:

Given,

x + y = 14 -----(1)

x - y = 4 -----(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:

x = 9 and y = 5

Step-by-step explanation:

x + y = 14

x - Y = 4

-- - - - - - - -

2 x = I8

x = 18 / 2

X = 9

x+ y = 14

9 + y = 14

y = 14 - 9

y = 5
