Which of the following is the solution to 6/(x+2) = 5/4x?
Oliga [24]

Answer:

The answer to your question is     x = 10/19

Step-by-step explanation:

Equation

                      6 / (x + 2) = 5 / 4x

To solve this equation use cross multiplication

                      6(4x) = 5(x + 2)

Simplify

                     24x = 5x + 10

Subtract 5x in both sides of the equation

                     24x - 5x = 5x - 5x + 10

Simplify

                     19x = 10

Divide by 19 both sides

                     19x/19 = 10/19

Simplify

                         x = 10/19
