Answer:

1. X > 1

2. 3/2

Step-by-step explanation:

For the first one, you must get x by itself in one side. to get rid of the Positive 3, you must subtract it from both the 3 and 10on the other side. Now u have 7x > 7. You then divide the seven from thr seven on one side and the seven on the other side. X> 1

number 2. multiplying is the opposite of dividing right? So you would multiply the 4 by what is on the other side, 3/8. 4 can also be written as a fraction, 4/1. When you multiply this out, you get 12/8 which is the same thing as 3/2.

i hope this helps u
