  1. Solving One-Step Equations & Inequalities

    Slide 1 - Solving One-Step Equations & Inequalities

    • Algebra Part 2A
  2. Solving Equations with Algebra

    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. Solving One-Step Equations Add & Subtract

    Slide 3 - Solving One-Step Equations Add & Subtract

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

    Slide 5 - Solving One-Step Equations Divide

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

    Slide 7 - Solving One-Step Equations Multiply

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

    Slide 9 - Review: Order of Operations

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

    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. Solving One-Step Inequalities

    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. Checking your Solutions to Inequalities

    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.
