Answer: x = -35

Explanation:

7/3x = 2/(x+5)

Use cross multiplication:

7(x+5) = 2(3x)
7x + 35 = 6x
35 = 6x - 7x
35 = -x
-35 = x

Step-by-step explanation:

Hey, there!!

[tex] \frac{7}{3x} = \frac{2}{x + 5} [/tex]

By cross multiplication,

[tex]7.(x + 5) = 2 \times 3x[/tex]

[tex]7x + 35 = 6x[/tex]

[tex]7x - 6x = -35[/tex]

Therefore, x= -35.

Hope it helps...
