Step-by-Step Solution

To solve the equation 8x+x5+3x=431+6x -8x + x - 5 + 3x = 4 - 3 - 1 + 6x , follow these steps:

  • Step 1: Simplify each side by combining like terms.
  • Step 2: Rearrange the equation to isolate x x .
  • Step 3: Solve for x x .

Let's solve the problem step-by-step:

Step 1: Simplify each side.

On the left side, combine the like terms 8x+x+3x -8x + x + 3x :

8x+x+3x=8x+4x=4x -8x + x + 3x = -8x + 4x = -4x

Thus, the left side becomes:

4x5 -4x - 5

On the right side, compute the constant terms first:

431=0 4 - 3 - 1 = 0

Therefore, the right side simplifies to:

0+6x=6x 0 + 6x = 6x

Now the equation is:

4x5=6x -4x - 5 = 6x

Step 2: Move all terms involving x x to one side.

Add 4x 4x to both sides to move the variable terms together:

4x+4x5=6x+4x -4x + 4x - 5 = 6x + 4x

This simplifies to:

5=10x -5 = 10x

Step 3: Solve for x x .

Divide both sides by 10:

x=510 x = \frac{-5}{10}

Thus, simplifying the fraction, we have:

x=12 x = -\frac{1}{2}

Therefore, the solution to the equation is x=12 x = -\frac{1}{2} , corresponding to choice 3.

Answer

12 -\frac{1}{2}
