Question

Solve the proportion 2 times x all over 5 times x plus 6 equals 2 over x.. What is the value of x?

Answer 1

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

x = -1 and x = 6 both work

2(-1) / (5(-1) + 6) = 2 / (-1)

- 2 / 1 = -2 / 1

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

12 / 36 = 1 / 3
1/3 = 1/3

Answer 2

if you move the x on the right to the left side of the equation by multiplying by x, you end up with a quadratic equation, hence the two answers

Answer 3

so are the aswers 1/3?

Answer 4

no, they're x = -1, and x = 6
