Question

Find the sum of x + y equals to 14 and x minus y equal to 24

Answer 1

Step-by-step explanation:

x+y = 14

or. x+y-14=0.............(1)

x-y=24

or x-y-24=0 ...........(2)

Now adding equation (1)&(2), we get

x+y-14+x-y-24=0

2x-38=0

2x= 38

x = 38/2

x = 19

& y = -5

Answer 2

Answer:

x = 19

y = -5

Step-by-step explanation:

x + y = 14 - EQUATION 1

x - y = 24 - EQUATION 2

x = 24 + y

Substituting the value of x :

24 + y + y = 14

24 + 2y = 14

2y = 14 - 24

2y = -10

y = -10 / 2

y = -5

So :

x - 5 = 14

x = 14 + 5

x = 19
