8.4 Elimination with Multiplication

Step #1 - Check to make sure that each equation is in the same form (Ax + By = C- standard form).
(Note: y = mx + b works also, but standard form is preferred.)
Step #2 - Decide which variable you are going to eliminate
Step #3 - Multiply (if necessary) to get x or y terms the same and solve.
Step #4 - Plug the solved value into one of your equations and find the other variable.
Step #5 - Check your solution.

Assignment: Extra Practice Worksheet

November 1st (B) and 2nd (A)

8.3 Solving systems by Elimination

Steps:

1. Put equations into same form: Standard form is highly suggested -> Ax + By = C
Make sure Equation #1 and #2 are in Standard Form.

2. Determine which variable to eliminate.

3. ADD or SUBTRACT

Note: If the two terms you are trying to eliminate have the same sign: SUBTRACT.
If the two terms you are trying to eliminate have different signs: ADD.

4. Solve!

8.2 Substitution

-- keeps it balanced!
--the two values must be equal!

Substitute means:
1. to put (something in place of another)
2. to take the place of; replace
3. to replace (one or more elements) with other elements

STEPS TO SOLVE A SYSTEM OF EQUATIONS BY SUBSTITUTION:

1. Solve ONE equation for ONE of the variables (Solve for x or y)
2. Substitute (replace) value of that variable into the OTHER equation
3. Solve that equation for the remaining variable
4. Find the value of the remaining variable (substitute again using equation from step 1)

Review:

As a class we worked on identifying the terms in an equation, and how to "move" the terms from one side of the equal sign to the other (opposite). Four VERY explicit examples were discussed, shown on the Promethian Board, and analyzed.

Review #3 (1.3) ORDER OF OPERATIONS

Remember that ORDER does matter!

Please Excuse My Dear Aunt Sally...

What does that mean?
1st - P = Parenthesis; grouping symbols such as parenthesis, brackets, fraction bar and absolute value.
2nd - E = Exponents
3rd - M = Multiplication
3rd - D = Division
5th - A = Addition
5th - S = Subtraction

In other words: PEMDAS must be the order that is followed.

Remember that Multiplication and Division happen at the same time; whichever comes first, from left to right. Remember that Addition and Subtraction happen at the same time; whichever of the two comes first, from left to right.
