Verify that the given value is a solution to the equation.
$a=2;4a+3=a+9$

• A. Solution
• B. Not a solution
• C. $a=2$ is not a valid solution

Answer: (A)

Verified step by step guidance

1. Identify the given value and the equation. Here, the value to verify is \(a = 2\), and the equation is \$4a + 3 = a + 9$.
2. 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$.
3. Simplify both sides separately. Calculate \(4 \times 2 + 3\) on the left side and \$2 + 9$ on the right side.
4. 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.
5. State your conclusion based on the comparison: confirm whether \(a = 2\) satisfies the equation or not.
