1. Solve the linear system.
Elimination Method:
Solve the linear system.
-8x + 3y=12 8x - 9y=12

2. Solve the linear system.
Solution: ( , )
Add the two equations together so that one variable is ELIMINATED.
Do you have inverse or identical terms?
+ 3y=12
- 9y=12
Inverse terms: Add
-8x +
Yes!
Inverse terms 8x
Now, solve for the remaining variable.
-6y = 24 -6 -4 -4
y =
Now what?

3. Solve the linear system.
Elimination Method:
Solve the linear system.
Solution: ( , -4 ) -4
Substitute value into one of the original equations.
-8x + 3y=12 8x - 9y=12 ( )
-8 x + 3
=12 y
Solve.
-8 x =12
+12
-8 x =24 -8 -3 -3
x =

4. Solve the linear system.
Elimination Method:
Solve the linear system.
Solution: ( -3 , -4 ) -3 -4
Check!!!!!
-8x + 3y=12 8x - 9y=12 ( ) x y
=12
=12
12 =12
