Step-by-Step Solution

To solve this problem, we'll follow the procedure of simplifying and solving for x x :

  • Step 1: Simplify both sides of the equation.
  • Step 2: Combine like terms and move them to opposite sides to isolate x x .
  • Step 3: Solve for x x by performing necessary arithmetic operations.

Now, let's work through each step:

Step 1: Simplify both sides of the equation.
The given equation is x+38x=4+3x x + 3 - 8x = 4 + 3 - x .
Combine like terms on each side:
Left side: x8x+3=7x+3 x - 8x + 3 = -7x + 3
Right side: 4x+3=7x 4 - x + 3 = 7 - x
So the equation becomes: 7x+3=7x -7x + 3 = 7 - x .

Step 2: Get all terms involving x x on one side of the equation.
Add x x to both sides to combine the x x terms:
7x+x+3=7x+x -7x + x + 3 = 7 - x + x
Simplifies to: 6x+3=7 -6x + 3 = 7

Step 3: Solve for x x .
Subtract 3 from both sides to isolate terms involving x x : 6x+33=73 -6x + 3 - 3 = 7 - 3 6x=4 -6x = 4
Now, divide both sides by 6-6 to solve for x x : x=46=23 x = \frac{4}{-6} = -\frac{2}{3}

Therefore, the solution to the problem is x=23 x = -\frac{2}{3} .

Answer

23 -\frac{2}{3}
