Step 1: Write the inequality as equation. x2 - 4x - 5 = 0 Step 2: Solve the equation. Here we can use any process of solving quadratic equations. Then (x - 5) (x + 1) = 0 x = 5; x = -1. Step 3: Represent the solutions from Step 2 on the number line and identify ...
3. Check all possible solutions. Remember to maintain inequality, we must perform the same operation to both sides of the equation. Solving Two Step Equations Involving Decimals This video provides examples of solving two step linear equations involving decimals. Examples: 0.3x - 2.16 = 9.9 x/...
