Create and solve equations, showing your work. you must create the equations and show the steps required to solve them.

your portfolio must include a minimum of the following types of equations:

one one-step equation
one equation that contains fractions
one equation with decimals
one real-world problem that is solved by an equation

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
