Question

If X/7=Y/5 then what does 5X equal

Answer 1

7y

Explanation:

By cross multiplication

`(x)/(7) = (y)/(5) \\ 5x = 7y`

Answer 2

`5x=7y`

Explanation:

We have the following relationship

`(x)/(7)=(y)/(5)`

Based on the relationship between the variables X and Y that we know, we must find out what the expression "5x" is in terms of the variable y.

Then we solve the equation for x

`x=(7y)/(5)`

Now multiply by 5 both sides of equality

`5x=(5*7y)/(5)`

`5x=7y`

Finally we have that 5x equals 7y
