There is only one solution and the solution is x=-22
You’ll need to divide 1,644 and 13 since the manager wants to put 1,644 polished rocks into small bags. And 13 rocks is how much will be in each bag. So you’ll do 1,644/ 15 = 109 with 6 left over. Hope it’s correct :)
Complementary angles have a submission of 90 degrees thus :

Add both sides 36


Divide both sides by 8

Answer:
No solutions
Step-by-step explanation:
First things first we need to get rid of the variables so we subtract -12x from one side to the other.
Now we have 1= -10
In this case, 1 is not equal to -10 so we get no solutions!
(Side note: if they were the same like 3=3 that would be all solutions.)
