Answer: x = -35

Step-by-step 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!!


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

By cross multiplication,


7.(x + 5) = 2 * 3x


7x + 35 = 6x


7x - 6x = -35

Therefore, x= -35.

Hope it helps...
