Your portfolio must include a minimum of the following five types of equations and solutions:
•two one-step equations

•two equations that contains fractions

•one equation with distributive property

•one equation with decimals

•one real-world problem that is solved by an equation

once you have created each equation, you will solve it and show your work. pretend that you are teaching the equations to a new pre-algebra student. or you can actually teach them to a sibling or friend!

Two one-step equations
x + 7 = 10
x = 7-7 = 10 - 7
x = 3

y + 47 = 20
y = 47 - 47 = 20 - 47
y = 27

Two equations that contains fractions
+ 
2 + 3 = 5
5/5 = 
or 1

+
12 + 7 = 19
19/20 = 


Distributive property
2x - 4(+4) = 10(+4)
2x - 16 = 40
2x - 16 + 16 = 40 + 16
2x = 56
56 ÷ 2 = 28
x = 28

Decimals
x = 1.2 + 7.8 ÷ 3(5)
1.2 + 7.8 = 9
9 ÷ 3 = 3
3 x 5 = 15
15.0

One real-world problem that is solved by an equation
Johnny deposits $2,000 into a bank account. If the interest rate is 5% per month how much will he have gained in interest in 6 years?
5% of 2,000 is 100
100 x 12 = 1,200
1,200 x 6 = 7,200
Johnny would gain $7,200 in 6 years

The answer is $9.90 with rounding to the nearest tenth

It says in the questions that it is 6.5?
