Answer:

  • See below

Explanation:

Solving all as well since it doesn't ask what is exactly required

1. The sum of a number (a) and 13 is 14 minus the same number (a).

  • a + 13 = 14 - a
  • a + a = 14 + 13
  • 2a = 27
  • a = 27/2
  • a = 13.5

2. The product of a number (c) and 7 is 42 divided by the same number (c).

  • c*7 = 42/c
  • c*c = 42/7
  • c² = 6
  • x = √6

3. A number (f) less than 27 is 82 divided by that same number (f).

  • 27 - f = 82/f
  • 27f - f² = 82
  • f² - 27f + 82 = 0
  • f = (27 ± √401)/2

4. 22 less than a number (m) is 19 times that same number (m).

  • m - 22 = 19m
  • 19m - m = -22
  • 18m = -22
  • m = -22/18
  • m = -11/9
