Section 3.5
Use the Distributive Property to solve equations
RECALL
Solving Equations – Procedure
1. Simplify the expressions on each side of the
equation
2. Collect all terms containing variables on the
same side of the equation
3. Isolate the variable
Example: Solve and Check your solution.
1. 4(x + 1) = 16
2. 2(6 + d) = -8
3. 5(t – 7) = 3
Practice: P143 Try This after Example 2
Practice: P144 #s 5-6
No solution and All real numbers
Examples: Solve each equation
1. 4m – 1 = 2(2m – 3) + 5
2. 6(m + 2) = 4m + 7 + 2m
Practice: P143 Try this after Example 3
Practice: P144 #s 8-9
Distributing the negative
Examples: Solve each equation
1. 5x – 2(3x + 7) = 7x + 12
Practice: P144 Try this after Example 4
Practice: P144 #s 7
Homework: P145 #s 13-43o
