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

• A. Solution
• B. Not a 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 the left side of the equation: replace \(a\) with 2 in \$4a + 3\(, which becomes \)4 \times 2 + 3$.
3. Simplify the left side expression: calculate \$4 \times 2$ and then add 3 to find the numerical value.
4. Substitute the given value \(a = 2\) into the right side of the equation: replace \(a\) with 2 in \(a + 9\), which becomes \$2 + 9$.
5. Simplify the right side expression and then compare the simplified left and right sides. If both sides are equal, then \(a = 2\) is a solution; if not, it is not a solution.
