What are Two-Step Equations??
Two-Step Equations are equations that have two operations . Or, there are __________ numbers to “get rid of” in order to _________________________ the variable!
To Solve a Two-Step Equation:
1) Zero Pairs (get rid of # that is being added/ subtracted)
2) Multiply or Divide
Examples: 3x + 2 = (“3” and “2” are the #’s with “x”)
(subtract “2” from both sides to make zero pair)
3x = (re-write equation)
(divide by 3 on both sides)
x = 8
_x_ + 3 = (“-2” and “3” are the #’s with “x”)
(subtract “3” from both sides to make zero pair)
_x_ = (re-write equation) -2
-2 • _x_ = 10 • (multiply by -2 on both sides)
x = -20
Multiplication Two-Step Equations:
2x + -3 = ) -5x – 6 = 29
3) x = ) = 9 – 9x

2. Division Two-Step Equations:
_x_ + -3 = ) _x_ – 6 = 56
10 + _x_ = ) = _x_
