Ex. 1
10 + x = 18
-10 -10
x = 8
Ex. 2
x - 8 = 9
+ 8 +8
x = 17
Ex. 3
22 = x - 11
+11 +11
33 = x
Ex. 4
Darius took a 34-mile trip in his car, and the odometer showed 16,550 miles at the end of the trip. What was the original odometer reading?
x + 34 = 16,550
-34 -34
x = 16, 516 miles
OR
The original odometer reading was 16,516 miles.

1-3 Solving One-Step Equations By Using The Inverse Operation
EQUATION - Uses and equal sign to show
that two expressions are equal.
SOLVE - When you find the value
of the variable that makes
the equation true.
SOLUTION - The answer to an equation.
INVERSE OPERATION - To "undo" an expression
or do the opposite.
ISOLATE THE VARIABLE - Get the variable alone.

1. What are the steps for solving one-step equations?

2. Solve.

x - 4 = 16
Ex. 1
10 + x = 18
Ex. 2
x - 8 = 9
Ex. 3
22 = x - 11
x + 34 = 16,550
Solve algebraically.

1. x + 4 = 22

2. x - 6 = 39

3. x/6 = 3

4. 16x = 12

5. The price of your favorite cereal is now $4.25.
