Solve for the variable "Y"

Answer


Part I


Y + (Y * 0.013) = 2,505,835.84

note: Y * 0.013 = 0.013 * Y = 0.013Y

Y + 0.013Y = 2,505,835.84

1Y + 0.013Y = 2,505,835.84

combine like terms

1.013Y = 2,505,835.84


Combine Like Terms





---------------------------------------------------

another way of looking at this is:

to simplify 1Y + 0.013Y, factor out the Y

1Y + 0.013Y

= Y(1 + 0.013)

= Y(1.013)

= 1.013Y

---------------------------------------------------

continuing with the solution:

divide each side of the equation by 1.013

1.013Y = 2,505,835.84

1.013Y / 1.013 = 2,505,835.84 / 1.013

Y = 2,505,835.84 / 1.013

Y = 2473678.0256663375


 Divide each side of the equation by 1.013

Part II


the final answer is:

Y = 2473678.0256663375


the final answer is:  Y = 2,473,678.0256663375






check the answer

substitute 2473678.0256663375 for Y in the original equation

Y + (Y * 0.013) = 2,505,835.84


2473678.0256663375 + (2473678.0256663375 * 0.013) = 2,505,835.84

2,505,835.84 = 2,505,835.84, OK → Y = 2473678.0256663375 is a valid solution
