Answer:
Step-by-step 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
