Answer:
Trying to solve this leads to an absurdity, so No Solution.
Step-by-step explanation:
5x+12=5x−7
Lets attempt to solve:
Subtract 5x from both sides
5x - 5x + 12 = 5x - 5x - 7
0 + 12 = 0 - 7
12 = -7
This is absurd so there is no solution.

Answer:
2(plus or minus) 1i
Step-by-step explanation:
First find the distance between the number that is being multiplied by the variable. Then, find the distance in absolute value between the numbers that have been added or subtracted.
3i - 2i = 1i
I 4 + -6 I
C is the answer to the question
Answer:
The offices can be filled in 3,360 ways
Step-by-step explanation:
In this question, we are faced with a selection problem.
There are three offices and 3 officers to be selected.
For the first position, we are to select 1 out of 16. Now, for the second position, we are left with 15 members from which we are to select one. This is because the first selection has been picked and cannot partake in the subsequent selections.
Likewise for the third position, we are selecting 1 out of 14
The number of ways this can be done is thus; 16C1 × 15C1 × 14C1 = 16 × 15 × 14 = 3,360 ways
