Step-by-Step Solution

To solve for x x in the given equation 2x+4+10x8=34x+17 -2x + 4 + 10x - 8 = 3 - 4x + 17 , follow these steps:

  • Step 1: Simplify both sides of the equation.
  • Start with the left-hand side of the equation:

    2x+4+10x8 -2x + 4 + 10x - 8 simplifies to:

    (2x+10x)+(48)=8x4 (-2x + 10x) + (4 - 8) = 8x - 4

    Now, simplify the right-hand side:

    34x+17 3 - 4x + 17 combines to:

    (3+17)4x=204x (3 + 17) - 4x = 20 - 4x

  • Step 2: Rearrange the equation to place all variable terms on one side and constant terms on the other.
  • We have:

    8x4=204x 8x - 4 = 20 - 4x

    Add 4x 4x to both sides to collect all x x -terms on the left:

    8x+4x4=20 8x + 4x - 4 = 20

    This simplifies to:

    12x4=20 12x - 4 = 20

  • Step 3: Solve for x x .
  • Add 4 to both sides to isolate the terms with x x :

    12x=24 12x = 24

    Finally, divide by 12 to solve for x x :

    x=2412=2 x = \frac{24}{12} = 2

Therefore, the solution to the equation is x=2 x = 2 .
