The process of solving 1-step equations
What is "to isolate the variable by doing the reverse operation for the equation"?
Name a method of solving 2-step equations?
What is "the box method"?
or
What is "do/undo"?
Isolate the variable by either dividing or multiplying on both sides of the equal sign
What is "the process of solving 1-step equations that include multiplication and division"
One-step equations
-Undo subtraction by adding to both sides
-undo addition by subtracting on each side.
-Undo multiplication by dividing on both sides
-undo division by multiplying on both sides
OR
use inverse operations

What step do I take to solve 15 = 3w?
Divide by 3 on both sides of the equal sign
Explain how to use the box method
1. look for how many numbers are in the equation & draw that number of boxes.
2. In the last box, write the number that is alone on the opposite of the variable.
3. write what operation happened in order on top (drawing arrows from one box to the next.)
4. write the inverse operations (undo steps) on the bottom with arrows going left
5. do the "undo" steps you just listed to solve
