Sure! Here's a simplified version of the problem:

6(x + 4) = 54

Real-life situation:
Suppose you and your friends go to a pizza restaurant. You ordered x number of pizzas, and each pizza costs $6. With an additional expense of $4 per pizza for delivery charges and taxes, the total bill comes out to be $54. Now, let's solve the equation using two different methods.

Method 1: Distributive Property
First, distribute the 6 to both terms inside the parentheses:
6(x) + 6(4) = 54
6x + 24 = 54

Then, isolate the variable by subtracting 24 from both sides of the equation:
6x + 24 - 24 = 54 - 24
6x = 30

Next, isolate the variable by dividing both sides of the equation by 6:
6x/6 = 30/6
x = 5

Method 2: Combine Like Terms
First, multiply the 6 with both terms inside the parentheses:
6(x + 4) = 54
6x + 24 = 54

Next, isolate the variable by subtracting 24 from both sides of the equation:
6x + 24 - 24 = 54 - 24
6x = 30

Lastly, divide both sides of the equation by 6 to solve for x:
6x/6 = 30/6
x = 5

In this scenario, both methods result in the same solution, which is x = 5. Method 2, combining like terms, may be slightly quicker for this equation as it skips an extra step of distributing. However, it ultimately depends on personal preference and familiarity with the different solution methods.
