Let n represent the number. You require
   7n - 2n = 55
   5n = 55 . . . . . . collect terms
   n = 11 . . . . . . . divide by 5

The number is 11.

You are basically just adding, so combine like terms.

3x^2 + 5x^2 = 8x^2

6x - 2x = 4x

4 - 8 = -4

So the answer is D.

44.


The closer it gets to -19, the closer the number goes to 44. It never hits it exactly though, but based off the trend (43.95, 43.995, 43.9995) we can tell that it gets closer to 44 each time.


Hope this helps! (:
