Answer:
x = 7
Step-by-step explanation:
To find the value of the value of x when
y = 14 we must first find the relationship between them
The statement
The value of y varies directly with x is written as
[tex]y \: \: \: \alpha \: \: \: kx[/tex]
where k is the constant of proportionality
when x = 218
y = 436
So we have
436 = 218k
Divide both sides by 218
k = 2
So the formula for the variation is
y = 2x
when y = 14
We have
14 = 2x
Divide both sides by 2
x = 7
Hope this helps you.
