1. ### Slide 1 - Solving One-Step Equations & Inequalities

• Algebra Part 2A
2. ### Slide 2 - Solving Equations with Algebra

• The goal of solving equations is to isolate the variable.
• In other words, “get the variable alone on one side”
3. ### Slide 3 - Solving One-Step Equations Add & Subtract

• To solve an equation using algebra, perform the opposite operation to both sides.
4. ### Slide 5 - Solving One-Step Equations Divide

• To solve an equation using algebra, perform the opposite operation.
5. ### Slide 7 - Solving One-Step Equations Multiply

• To solve an equation using algebra, perform the opposite operation.
6. ### Slide 9 - Review: Order of Operations

• When you are given a multi-step problem, you can use Order of Operations to simplify it.
7. ### Slide 10 - Checking your Solutions

• After solving an equation you should always check your solution. You do this by substituting your solution in for the variable and checking that the final statement is true.
• Yes. This is true.
8. ### Slide 12 - Solving One-Step Inequalities

• Inequalities can be solved in the same way as equations with ONE special rule:
• When multiplying or dividing by a negative, flip the sign.
9. ### Slide 14 - Checking your Solutions to Inequalities

• To check your solution to inequalities, choose a number that fits your solution to test. Your final statement should be true.
• Let’s try -5
• Yes. This is true.
