First you are going to distribute and you are going to get 8c-72=12c-72-4c.
Next you are going to combine like terms you get 8c-72=8c-72.
Then move the Varible to one side and solve for the Varible you should get c=0
Answer:
The simple interest formula is I =PrT
Here I = 378, P = 1800, T = 2
substitute
378 =1800*r*2
r = 378/3600 = .105, i.e. 10.5%
