    Question Need some algebra help please

    I need help trying to learn how to set up equations. Barton and Gonzalez invested 195,000 in a business venture. If Gonzalez invested 2 1/2 times as much as Barton, how much did he invest?


    I am trying to learn how to set up equations and solve them I have never had algebra before so it is a struggle for me. Please help if you can? Thank you

    this is a very simple problem. but if you haven't had algebra, it's gonna be the equivalent of me looking at calculus (i've yet to have it).

    Let b = Barton's\;\;money\;\;invested
    Let g = Gonzalez's\;\;money\;\;invested

    Barton and Gonzalez invested 195,000 in a business venture.
    You can make the equation: b + g = 195,000

    Because that says exactly what is quoted above.

    ...Gonzalez invested 2 1/2 times as much as Barton...
    So whatever amount Barton invested, Gonzalez's amount is gonna be 2 1/2 times that amount.

    You can make this equation: g = 2.5b

    So you have this system:

    b + g = 195,000
    g = 2.5b

    Understand?
