Solving an Equation: Means finding the value of the unknown variable that makes the equation true.

Step 1 (Simplify Both Sides): Start by expanding any brackets and combining like terms on each side of the equation.

Step 2 (Rearrange the Equation): Move all terms with the unknown to one side and constants to the other.

Step 3 (Isolate the Variable): Divide both sides by the coefficient of the unknown variable to find its value. For instance, if $5x = 15$, then $x = 3$.
