The value of y varies directly with c. If x = 2, then y = 7. Find the value of x if y = 84.

Since the value of y is directly proportional to the value of x, when y = 84, x is equal to 24.

Given the following data:

To find the value of x if y = 84:

Since the value of y varies directly with x.

This ultimately implies that, the value of y is directly proportional to the value of x.

Mathematically, this is represented as follows:

First of all, we would determine the constant of proportionality (k).

Substituting the given parameters into the formula, we have;

Now, we can solve for x when y = 84:

x = 24

x=24

Step-by-step explanation:

y = x*c

x=2, y=7

2*c=7 => c=7/2

x*7/2 = 84

x = 84*2/7

x = 12*2

x = 24
