1. 8.5 Solving Equation with Variables on Each Side

2. X Finds His Value

3. Steps to solve multi-step linear equations
Collect like terms
Move variables to same side of equation. (using the Add/ sub prop of =)
Move the constant to the opposite side of the equation (using the Add/ sub prop of =)
Solve for x (using the Mult/div prop of =)

4. Example 1:
2x – 2 = -3x + 3
+ 3x
5x – 2 =

5. Example 2:

6. Example 3: 6m +5 – 2m = 10 – 3m +16 4m +5 = 26 – 3m +3m 7m +5 = 26 -5

7. Example 4: -2.2 +0.3z = 3- 0.5z -0.8z +1.3z +1.3z -2.2 +1.6z=3 +2.2

8. Example 5:

9. # of DVD’s = x Netflix: 50 + 1.99x Blockbuster: 3.99 x
Netflix charges a yearly membership fee of $50 plus $1.99 per DVD rental. The Blockbuster store has no membership fee and charges $3.99 per DVD rental. Write an equation and solve to find the number of DVD’s for which the cost of each would be the same.
# of DVD’s = x
Netflix: x
Blockbuster: 3.99 x
