SWBAT solve two-step algebraic equations.

Two-Step Equations are equations that require two-steps to solve. You will ADD or SUBTRACT and then
MULTIPLY or DIVIDE.
33xx + 8 = 29 + 8 = 29

Coefficient – The number that is attached to a variable
33xx + 8 = 29 + 8 = 29CoefficientCoefficient

To get rid of the coefficient, you will either MULTIPY or DIVIDE

The constant is the number that is not attached to a variable. It MUST be on the same side of the equal sign
as the variable.

To get rid of the constant, you will either ADD or SUBTRACT
You get rid of the constant FIRST!!

4x + 12 = 20

To solve two-step equations, you do order of operations in REVERSE
This means that you do addition or subtraction FIRST.
THEN you do multiplication or division.

22xx + 4 = 10 + 4 = 10 22xx - 4 = 10 - 4 = 10
55xx + 12 = 32 + 12 = 32 33xx + 6 = 27 + 6 = 27
99xx + 9 = 18 + 9 = 18 66xx + 12 = 18 + 12 = 18
55xx - 15 = 20 - 15 = 20 88xx + 10 = 42 + 10 = 42
