Answer:
x=2.6

Explanation:

Given the following equation:

(1.2)/(8)=(3)/(5x+7)

You need to solve for the variable "x" in order to find its value.

To do this, you can follow the steps below:

1. Youst must multiply both sides of the equation by
5x+7 :

$(5x+7)((1.2)/(8))=((3)/(5x+7))(5x+7)\\\\(6x+8.4)/(8)=3$

2. Now you have to multiply both sides of the equation by 8:

$(8)((6x+8.4)/(8))=(3)(8)\\\\6x+8.4=24$

3. The next step is to subtract 8.4 from both sides of the equation:

$6x+8.4-(8.4)=24-(8.4)\\\\6x=15.6$

4. And finally, divide both sides of the equation by 6:

$(6x)/(6)=(15.6)/(6)\\\\x=2.6$
