    One step equation, where only one step is required to solve the problem. Example:

    20 = 5x

    4 = x

    Fractions:

    1/2 + x = 3/2

    x = 3/2 - 1/2

    x = 1

    Decimals:

    0.5 + x = 1.5

    x = 1.5 - 0.5

    x = 1

    Real world problem: (word problem and equation)

    It costs $5 per hour to rent a canoe plus a $3 rental fee. How much will the total be if you plan on renting the canoe for 3 hours?

    y = 5x + 3

    y = total cost; x = number of hours rented

    y = 5*3 + 3

    y = 15 + 3

    y = $18
