Practicing One Step Algebraic Equations and Solving Two Step Algebraic Equations

Today in class, we started off by practicing one step algebraic equations.


3+a=10 b-2=6 3c=9 D=2
3+a-3=10-3 b-2+2=6+2 3 3 5
a=7 b=6 c=3 Dx5=2x5
3+a=10 b-2=6 3c=9 5
3+7=10 8-2=6 3(3)=9 D=10
10=10 6=6 9=9 D=2
5
10=2
5
2=2



Solving two step algebraic equations
*Dude pays $19 for 2 t-shirts and a pair of sunglasses.
How much does dude pay for each t-shirt?

If sunglasses cost $7.00 how much are the t-shirts?
Write an equation

2t+7=19
2t+7-7=19-7 Reverse Order of Operations
2t=12
2 2
t=6
2t+7=19
2(6)+7=19
12+7=19
19=19


Chick saw a sign saying buy two pants and get socks for $2 a pair. If she pays $30 for 2 pants and 4 pairs of socks. What is the price of a pair of pants?
Model using blocks on a scale.

P=pants Socks cost $8





2p+8=30
-8 -8
2p=22
2 2
p=11
2p+8=30
2(11)+8=30
30=30

H.W.
1. 3w+3=6
2. 2n+4=10

  2. Great job Glenesse. I like that your scribe is neat, organized and easy to understand. I also like the pictures and the different coloured words to make them pop out. It would have been nicer if the computer didn't mess up the first part.

  3. Great job Glenesse. Aside from the first part, your scribe is very neat and understandable. I really liked the site and the video. Next time try to make sure your computer doesn't mess up your scribe again.

  4. Great post Glenesse!! Your post was really neat except for the first part but next time I think it would be a good idea to not use as many different colors. Other than that, great job!!!
