Answer:

Third option

Explanation:

Given the following question:


7x-4=5x+15

To find the answer we need to use inverse of operations to simplify the equation in till we isolate the variable and find the value of x.


7x-4=5x+15

-4+4=0

15+4=19

7x=5x+19

5x-5x=0

7x-5x=2x

2x=19

2x/2=x

19/2=(19)/(2)

=(19)/(2)

Your answer is the third option or "19/2."

Hope this helps.
