Option b is correct answer
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 :)
