Question

Find the value of x and y where x+y = 14 x-y = 4​

Answer 1

x = 9

y = 5

Step-by-step explanation:

(x + y) - (x - y) = 14 - 4

x + y - x + y = 10

x - x + y + y = 10

2y = 10

y = 5

x + y = 14

x + 5 = 14

x = 14 - 5

x = 9

x - y = 4

x - 5 = 4

x = 4 + 5

x = 9

therefore, x = 9 and y = 5

Answer 2

Answer:

to find x and y

Step-by-step explanation:

(x + y) - (x - y) = 14 - 4

x + y - x + y = 10

x - x + y + y = 10

2y = 10

y = 5

x + y = 14

x + 5 = 14

x = 14 - 5

x = 9

x - y = 4

x - 5 = 4

x = 4 + 5

x = 9  

thus, x = 9 and y =5
