Period For Interest = 9 months
Period taken = 54 months
Investment = 2000
Quarters for payment = 54 ÷ 9

2000×2 = 4000
4000×2 = 8000
8000×2 = 16000
16000×2 = 32000
32000×2 = 64000
64000×2 = 128000

There are two parts of an equation (including this one), the coefficient, and the variable.
The coefficient is a known number, written as a digit, whereas the variable is an unknown number, written as a letter to signify an unknown number.
So, the coefficient in the first term (or part of the equation) is -2. The coefficient in the second term is 9, and the variable in this equation is x.
