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
