Solution to an equation:
Solution to an equation is the value that satisfies the equation.
Consider the equation \(x + 2 = 4\).
Value (\(x\)) | Equation (\(x + 2 = 4\)) | Equation satisfied or not? |
\(1\) | \(1 + 2 = 4\) | No |
\(2\) | \(2 + 2 = 4\) | Yes |
\(3\) | \(3 + 2 = 4\) | No |
\(4\) | \(4 + 2 = 4\) | No |
From the above tabular column, it is understood that the equation \(x + 2 = 4\) is satisfied only if '\(x\)' takes the value as \(2\).
Therefore, the solution to the equation \(x + 2 = 4\) is \(x = 2\).
