    3 (x-1) - 8=4 (1+x) + 5

    One solution was found:

    x = - 20

    Rearrange:

    Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

    3 * (x-1) - 8 - (4 * (1+x) + 5) = 0

    Step by step solution:

    Step 1:

    Equation at the end of step 1:

    ((3• (x-1)) - 8) - (4• (x+1) + 5) = 0

    Step 2:

    Equation at the end of step 2:

    (3 • (x - 1) - 8) - (4x + 9) = 0

    Step 3:

    Step 4:

    Pulling out like terms:

    4.1 Pull out like factors:

    -x - 20 = - 1 • (x + 20)

    Equation at the end of step 4:

    -x - 20 = 0

    Step 5:

    Solving a Single Variable Equation:

    5.1 Solve : - x-20 = 0

    Add 20 to both sides of the equation:

    -x = 20

    Multiply both sides of the equation by (-1) : x = - 20

    One solution was found:

    x = - 20

    hope this is wht u wanted
