Solve equations with one-step
Solve equations with one-step 1. What is a One-Step Equation? An equation is like a balanced scale. It says that the value on the left side is exactly the same as the value on the right side. A 'one-step' equation means you only need to perform one mathematical operation to find the value of the missing variable (usually x). The Golden Rule of Algebra: Whatever you do to one side of the equation, you MUST do to the other side to keep it balanced. 2. Inverse Operations To solve an equation, we use the 'opposite' or inverse operation to isolate the variable (get it by itself). Operation in Equation Inverse (Opposite) Operation Addition (+) Subtraction (-) Subtraction (-) Addition (+) Multiplication (x) Division (÷) Division (÷) Multiplication (x) 3. Step-by-Step Examples Example 1: Addition Equation: x + 8 = 15 Step: Subtract 8 from both sid...
