Describe the similarities and differences in the solution of 2x - 7 = 15 and 2x - 7 < 15

Both solutions will have values that exist at the "11" value. However, the major difference is due to one being an equation and the other an inequality. The first equation only has one solution. The inequality has infinitely many solutions, and they are all the values that are less than 11 (x<11).
