Move all variables to one side of the “=“ using inverse operations (+ or -)
Move all constants (numbers) to the other side of the “=“ using inverse operations (+ or -)
Get rid of the constant (number) attached to the variable by either (x or ÷)
REMEMBER: IF YOU MULTIPLY OR DIVIDE BY A NEGATIVE NUMBER YOU MUST FLIP THE SIGN!!!!!!

4. The following symbols need to be memorized….
When graphing inequalities the symbol tells you what type of dot you should have.
Hint: If there is a solid line under the symbol you should have a solid dot!
