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

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
