Find the unknown value in each proportion

Answer:Answer:

x = 15

Solution by Cross Multiplication

For the equation

58=x24

The cross product is

5*24=8*x

Solving for x

x=5*248

and reducing

x=15

Solution by Proportion

Since the equation is an equality

If

24 : 8 = 3

Then it is true that

x : 5 = 3

Solving for x

x = 5 * 3

x = 15
