Transcript Lesson 4.4

Bellringer
• Solve for each variable
1. -2x + 4 = 8
2. x + 3 – 2x = 5
3. 4x = 6x + 4
4.4 Using the Properties
Together
Solving Inequalities
• We use the addition and multiplication
properties together in much the same way as
we do for equations.
• We use the addition or subtraction property
first then the division property.
