## Working with Alge-Tiles Brackets

3(x+4)

Step1 :
Express whatever is in the bracket using
Alge-tils
Step2 :
Express whatever you had in step 1,
three times
(because this 3 is being multiplied by the bracket)
Step3 :
Simplify
3x+12

## Working with Alge-Tiles (Equations)- One Step

Step 1:
Use Alge-Tiles to represent the
equation.
Step 2:
To isolate the x-tiles, Use an
appropriate number of negative
(red) ones tiles

Step 3:
Interpret your tiles. Write the value of x.

X=4

## Working with Alge-Tiles (Equations)- Multi-step

Step 1:
Use Alge-Tiles to solve.
Step 2:
Use a flow chart to solve.
Step 3:

Ex.
Step 1:
2x-3=1
·         Isolate the x-terms
·         Keep the equation balanced
·         Remove zero pairs
·         Simplify
Step 2:
2x-3=1
Start with x à multiply by 2 – Subtract 3àresult is 1
GO BACK WARDS DOING THE OPPOSITE!
Step 3:
Check your solution by substituting it back into the equation.
Left Side (L.S)                                 Right Side (R.S)
= 2x – 3                                            = 1
=2(2) – 3
= 4 – 3
=1                                L.S=R.S

## Algebraic word Problems

Ex.
Ms. Akber is 5 years older than Jared. Find an expression for each of their ages.

There are two ways we can do this:
1. Express Ms, Akber’s age in thermos of Jared’s age.
2. Express Jared’s age in terms of Ms. Akber’s age.

*Trick à You use only one variable*
-Ex. 7xß Variable
Let Jared’s age be j.
Let Ms. Akber’s age be j+5.
