Question

Find x when y= 14, if y=7 when x=8

Answer 1

Answer: The required value of x is 16.

Step-by-step explanation: Given that the value of y is 7 when the value of x is 8.

We are to find the value of x when y is 14.

The ratio of y to x is given by

`y:x=7:8.`

Therefore, when y = 14, we must have

`14:x=7:8\\\\\\\Rightarrow (14)/(x)=(7)/(8)\\\\\\\Rightarrow x=(14*8)/(7)\\\\\Rightarrow x=16.`

Thus, the required value of x is 16.
