How to Solve the Equation 9x - x - 4 = 0

Solving the equation 9x - x - 4 = 0 involves combining like terms and isolating the variable. Here's a quick guide to solving it:

1. Combine the like terms (9x and -x) to simplify the equation.
2. Move the constant term (-4) to the other side of the equation.
3. Solve for x by dividing both sides by the coefficient of x.

The solution to the equation is x = 0.5. Use our calculator to verify this or try similar equations.

Step-by-Step Solution

Let's break down the solution process for the equation 9x - x - 4 = 0:

1. Combine Like Terms

   First, combine the terms with x:

   9x - x = 8x

   Now the equation becomes: 8x - 4 = 0

2. Isolate the Variable Term

   Move the constant term (-4) to the other side of the equation:

   8x - 4 + 4 = 0 + 4

   This simplifies to: 8x = 4

3. Solve for x

   Divide both sides by 8 to solve for x:

   x = 4 / 8

   x = 0.5

Worked Example

Let's solve a similar equation to reinforce your understanding:

Solve 7x - 2x - 3 = 0

1. Combine like terms: 7x - 2x = 5x → 5x - 3 = 0
2. Move the constant: 5x = 3
3. Solve for x: x = 3/5 → x = 0.6

The solution is x = 0.6. Practice with different equations to build your algebra skills.
