STEPS TO SOLVE EQUATIONS WITH VARIABLES ON BOTH SIDES!!!

DISTRIBUTE (if necessary)
COMBINE LIKE TERMS ON EACH SIDE OF = (if necessary)
MOVE VARIABLE TO LEFT SIDE OF =
MOVE CONSTANTS TO RIGHT SIDE OF =
SOVE !

EQUATION WITH SPECIAL CASES

ONE SOLUTION: 3X = 15 OR X = 5 (ONLY 1 x value makes true)

NO SOLUTION: 3X = 5X OR 5 = 9 (NEVER TRUE with any x)

INFINITE SOLUTION: 3X = 3X OR 5 = 5 (ALWAYS TRUE with any x)
