    Making Equations

    I am having difficulty with problems of this type:

    Write and solve an equation to find each amount of money:

    1.) An amount of money is increased by $6 is $13.

    2.)Two dollars less than an amount of money is $17.

    3.)One third an amount of money is $8.

    Thanks

    1.) An amount of money is increased by $6 is $13.
    x + 6 = 13
    x = 7


    2.)Two dollars less than an amount of money is $17.

    x - 2 = 17
    x = 19


    3.)One third an amount of money is $8.

    x/3 = 8
    x = 24

    Re: Making Equations

    1. An amount of money = $'x'$

    increased by= '+'

    Equation is $\Rightarrow x + 6 = 13\;\implies x=7$

    2. less than= '-'

    an amount = $'x'$

    equation is $x-2= 17\;\implies x=-15$

    3. One third an amount = $\dfrac{x}{3}$

    equation is = $\dfrac{x}{3}=8\;\implies x =24$

    No, $x= 17+ 2= 19$.

    3. One third an amount = $\dfrac{x}{3}$
