Question

Solve the proportion. * X-3 5 8. X= (Type an integer or a an integer or a simplified fraction.)

Answer 1

We want to solve the proportion:

`(x-3)/(x)=(5)/(8)`

For doing so, we remember that solving a proportion equivals to find the variable x. We will multiply means and extremes:

`\begin{gathered} 8(x-3)=5\cdot x \\ 8x-24=5x \\ \text{Now, we solve for x:} \\ 8x-5x=24 \\ 3x=24 \\ x=(24)/(3)=8 \end{gathered}`

This means that the value of x is 8, which is the solution of the proportion.
