First off, an inequality means that there is no equals sign... it will be either greater than (>) or less than (<). So we'll solve yours with the assumption that it is supposed to be greater than...
2s + 5s + 12 > 132
7s + 12 > 132
7s > 132 - 12
7s > 120
s > 120/7
s > 17 1/7
**If it was supposed to be less than instead of greater than, just change the sign. It doesn't affect the outcome.
1. write in standard form
2. group like terms
3. combine like terms
4. distribute the negative
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one
m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one
The answer is Subtraction
