The sum of two numbers is 56 and the difference is 14. what are the numbers?

x=35, y=21. (35, 21).

Step-by-step explanation:

x+y=56

x-y=14

2x=70

x=70/2

x=35

35+y=56

y=56-35

y=21

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
