Solve for u. u + 6 = 18

u = 3

u = 12

u = 24

u = 108

The value of u is 12

Step-by-step explanation:

u + 6 = 18

Subtract 6 from both side we get,

u + 6 - 6 = 18 - 6

u = 12

Thus, The value of u is 12

u + 6 = 18

12 + 6 = 18

18 = 18

L.H.S = R.H.S

Hence Proved!

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
