Answer:

-7

Step-by-step explanation:

You first multiply both sides by 10 to get rid of the decimal points, we don't want them.

25x + 100 = 10x - 5

Then, you subtract 100 from both sides:

25x = 10x - 105

Then, you subtract 10x from both sides:

15x = -105

Lastly, you divide by 15 on both sides:

x = -7

So, your answer is -7 :)
