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\$.
