5x + 43 = 42 5x = -1 x = -1/5 Check it. -2 + 43 + 1 = 42 42 = 42 Check.
It is 14/2.
Answering your question fully would be tediously time-consuming and counterproductive. The intent of this forum is to give you information and perhaps an example or two so that you can solve such problems yourself. Let's choose a random number like 42. Most people find a factor tree to be helpful. 42 Divide by two. 21,2 Divide by three. 7,3,2 Stop. The prime factors of 42 are 2, 3, and 7 Some numbers in that range are prime, like 43. The prime factor of 43 is 43. Now you try it.
When you have an even number of numbers, you find the median by averaging together the two middle values, in this case 42 and 44. Add the two numbers (42+44=86) and divide by 2 (86/2 = 43).
2/34, 2/43, 3/24, 3/42, 4/23, 4/32 are some examples.
5x + 43 = 42 5x = -1 x = -1/5 Check it. -2 + 43 + 1 = 42 42 = 42 Check.
Average. (42+43)/2 = 42.5 Come on.
42 is composite, 43 is prime.
21 with 1 remaining 43 - 1 = 42 = 2 x 21

It is 14/2.
