1. The problem states: If $x=2$ and $y=3$ is a solution of the equation $$8x - ay + 2a = 0,$$ find the value of $a$. 2. Substitute $x=2$ and $y=3$ into the equation: $$8(2) - a(3) + 2a = 0$$ 3. Simplify the expression: $$16 - 3a + 2a = 0$$ 4. Combine like terms: $$16 - a = 0$$ 5. Solve for $a$: $$a = 16$$ Therefore, the value of $a$ is $16$.
