1. 1-3 Solving Equations Big Idea: -Solve equations and inequalities

2. Solving Equations Solution of the equation: a number that makes the equation true. Solution

3. Properties of Equality Reflexive Property x = x Symmetric Propertyif a = b then b = a Transitive Property if c = d and d = e then c = e Addition Property if x = 5 then x +3 = 5 + 3

4. Subtraction Property if y = 2 then y – 1= 2 -1 Multiplication Property if w = 6 then 3w = 3·6 Division Property if a = 10 then a/2 = 10/2 Substitution Property if a = 2 and a + 3 then 2 + 3

5. Ex 1: Solve. A) 7x + 3 = 2x - 12 B 4(m + 9) = -3(m – 4)

6. Ex 2: The formula for the surface area of a rectangular prism is A = 2(lw + lh + wh). Solve the formula for w.

7. Ex 3: Solve for x. Find any restrictions on a and b.
