1.20x+5x = 75 what is x

2.10x-4x=28

1. 20x + 5x = 75

25x = 75

To find the answer, divide 75 by 25. The answer is 3.

2. 10x - 4x = 28

6x = 28

That's actually 4.6 repeating. Is that the problem we were supposed to do, or did you make a mistake? In any case, do tell me in the comments whether it was correct, or whether that is indeed the problem for #2.
