Identify the given value and the equation. Here, the value to verify is \(a = 2\), and the equation is \(4a + 3 = a + 9\).
Substitute the given value \(a = 2\) into both sides of the equation. Replace every \(a\) with 2, so the left side becomes \(4 \times 2 + 3\) and the right side becomes \(2 + 9\).
Simplify both sides separately. Calculate \(4 \times 2 + 3\) on the left side and \(2 + 9\) on the right side.
Compare the simplified results from both sides. If both sides are equal, then \(a = 2\) is a solution to the equation; if not, it is not a solution.
State your conclusion based on the comparison: confirm whether \(a = 2\) satisfies the equation or not.
