Solve the Linear Equation: 2a + 3a + 45a = 0

To solve the equation $2a + 3a + 45a = 0$, follow these steps:

• Step 1: Combine Like Terms.

Add the coefficients of $a$:

$2 + 3 + 45 = 50$

• Step 2: Substitute and Simplify.

This simplifies the equation to:

$50a = 0$

• Step 3: Solve for $a$.

To find $a$, divide both sides of the equation by 50:

$a = \frac{0}{50}$

$a = 0$

Therefore, the solution to the problem is $a = 0$.
