Step-by-Step Solution

To solve for x x , let's follow these steps:

  • Step 1: Combine like terms on both sides of the equation.
  • Step 2: Isolate the x x terms on one side.
  • Step 3: Solve for x x .

Let's begin with the left side of the equation:
5x+203x -5x + 20 - 3x simplifies to 8x+20 -8x + 20 .

Next, the right side of the equation:
40+26x 40 + 2 - 6x simplifies to 426x 42 - 6x .

The equation now is:
8x+20=426x -8x + 20 = 42 - 6x .

Step 2: Move all terms containing x x to one side and constant terms to the other:

First, add 8x 8x to both sides to move the x x terms together:
8x+8x+20=42+2x -8x + 8x + 20 = 42 + 2x
which simplifies to 20=42+2x 20 = 42 + 2x .

Next, subtract 42 42 from both sides to get:
2042=2x 20 - 42 = 2x
which simplifies to 22=2x -22 = 2x .

Step 3: Solve for x x by dividing both sides by 2:
x=222=11 x = \frac{-22}{2} = -11 .

Therefore, the solution to the problem is x=11 x = -11 .

Answer

11 -11
