If x=34y and y=16, what is the value of 3x-1?

Hi there!

If x is equal to 34 times y and y is equal to 16 then multiply 34 by 16, like so:

34 × 16 = 544

Then replace x in the equation with 544 and solve, like so:

(3 × 544) - 1 = 1631

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
