Example 1:
Solve the equation to the right.
Remember DCI!
6
Step 1: Distribute
The D of DCI
You need to distribute 8 to all terms within the parantheses
7
Step 2: Combine like terms
This is the C of DCI
The left side does not have any like terms so it is "cleaned up"
The right side has an 8x and a -5x which will combine to 3x
8
Step 3: Solve Using Inverse Operations
The I of DCI
Move all your variables to one side and constants to the other side. Then solve for the variable....
9
Step 4: Check
substitute your answer into all variables in the original equation

Example 2:
Remember DCI!
D: Distribute the -4 first
C: Combine like terms on left
I: Inverse Operations - subtract 4 from both sides and then divide by them both by -4
