1.  1. Discuss HW
 2. Solving Equations with Separated
Unknowns
 3. Solving Equations with Parentheses
 4. Practice

2.  When the unknowns are separated, you must
combine them before solving.
 5x + 2x = 7x
 4a + a = 5a
 6c-5c = c
 m + m = 2m

3.  Solve for x in 5x – 2x +8 = 26
Step 1: Combine like
terms.
Step 2: Subtract 8 from
-8 -8 both sides.
Step 3: Divide by 3 on
3 3 both sides.
x=6

4.  Solve for a in 9a – 3 = 2a +11
Step 1: Subtract 2a
from both sides.
-2a -2a
Step 2: Add 3 to both
+3 +3 sides.
Step 3: Divide both
sides by 7
7 7

5.  Complete Exercise 11

6.  Use the distributive property to simplify, combine
like terms and numbers, then solve for the unknown.
Step 1: Apply the distributive
property.
Step 2: Add x to each side.
Step 3: Subtract 6 from each
side.
Step 4: Divide both sides by 7.

7.  Complete Exercise 12 and do some extra
practice on pages 74-75.
