Math 8

CHAPTER 2-2: SOLVE TWO-STEP EQUATIONS
1. Use the ADDITION/SUBTRACTION PROPERTIES OF EQUALITY
(get rid of addition or subtraction)
2. Use the MULTIPLICATION/DIVISION PROPERTIES OF EQUALITY
(get rid of multiplication/division)

If both the constant is a fraction and the coefficient is also a fraction, sometimes it’s better to get rid of the denominators by multiply by the LCM of all the denominators first:
When there is addition or subtraction in the numerator and a constant (number) in the denominator, multiply by the denominator first!
Then you’ll have a simple one-step equation after that ;)
