How do you solve the equation x + 4x + 4 = 9?

by

To solve the equation x + 4x + 4 = 9, we first need to combine like terms and simplify it. Here’s how to do that step by step:

  1. Combine the terms with x. You have x + 4x, which simplifies to 5x. So the equation now looks like:

    2. 5x + 4 = 9

  2. Next, we want to isolate 5x by subtracting 4 from both sides of the equation:

    3. 5x + 4 – 4 = 9 – 4

    This simplifies to:

    5x = 5

  3. Now, to find the value of x, divide both sides of the equation by 5:

    4. x = 5 / 5

    This gives us:

    x = 1

So, the solution to the equation x + 4x + 4 = 9 is x = 1.
