Answer 3

Solving the Equation 4.5a - 54 = a + 72

To solve the equation 4.5a - 54 = a + 72, we can follow these steps:

1. Combine like terms on the same side of the equation. 2. Isolate the variable to solve for its value.

Let's solve the equation step by step.

Step 1: Combine Like Terms

First, let's combine the like terms on each side of the equation.

Subtract 'a' from both sides: 4.5a - a - 54 = 72

Combine the 'a' terms: 3.5a - 54 = 72

Step 2: Isolate the Variable

Add 54 to both sides to isolate the variable 'a': 3.5a = 72 + 54 3.5a = 126

Now, divide both sides by 3.5 to solve for 'a': a = 126 / 3.5 a = 36

The value of 'a' that satisfies the equation 4.5a - 54 = a + 72 is 36.
