1. 2.3 Solving Multi-Step Equations
Combining like terms
Solve each equation.
a. 2c + c + 12 = 78
3c + 12 = 78
3c = 66
c = 22
4b b = 46
6b + 16 = 46
6b = 30
b = 5

2. Solving an Equation with Grouping Symbols
Solve -2(b – 4) = 12
-2b + 8 = 12
-2b = 4
b = -2

3. Solving an Equation that Contains Fractions
Solve

4. Solving an Equation that Contains Decimals
Solve 0.5a = 13.25
100(0.5a ) = 100(13.25)
100(0.5a) + 100(8.75) = 100(13.25)
50a = 1325
50a = 450
a = 9

5. Steps for Solving a Multi-Step Equation
Clear the equation of fractions and decimals.
Use the Distributive Property to remove parentheses on each side.
Combine like terms on each side.
Undo addition or subtraction.
Undo multiplication or divison.
