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.
