5x + 4(x + 3) = 66

It's your turn now. How do YOU think this problem should be solved?

5x + 4 x + 12 = 66

9x = 54
x = 6

Sorry, did not realize this was a second question.

To solve the equation 5x + 4(x + 3) = 66, we will follow these steps:

Step 1: Distribute the 4 to both terms inside the parentheses:
5x + 4(x + 3) = 66 becomes 5x + 4x + 12 = 66.

Step 2: Combine like terms on the left side of the equation:
5x + 4x + 12 = 66 simplifies to 9x + 12 = 66.

Step 3: Move the constant term (12) to the right side of the equation:
9x + 12 = 66 becomes 9x = 66 - 12.

Step 4: Simplify the right side of the equation:
9x = 54.

Step 5: Divide both sides of the equation by the coefficient of x (9):
9x/9 = 54/9 simplifies to x = 6.

Therefore, the solution to the equation 5x + 4(x + 3) = 66 is x = 6.
