    4=x

    Step-by-step explanation:

    6-3 (x-5) = 5x-11

    Distribute the - 3

    6 - 3x + 15 = 5x - 11

    Combine like terms

    21 - 3x = 5x-11

    Add 3x to each side

    21-3x+3x = 5x+3x-11

    21 = 8x-11

    Add 11 to each side

    21+11 = 8x-11+11

    32 = 8x

    Divide by 8

    32/8 = 8x/8

    4 = x

    6 - 3x + 15 = 5x - 11

    Simplify 6 - 3x + 15 to - 3x + 21

    -3x + 21 = 5x - 11

    Add 3x to both sides

    21 = 5x - 11 + 3x

    Simplify 5x - 11 + 3x to 8x - 11

    21 = 8x - 11

    Add 11 to both sides

    21 + 11 = 8x

    Simplify 21 + 11 to 32

    32 = 8x

    Divide both sides by 8

    32/8 = x

    Simplify 32/8 to 4

    4 = x

    Switch sides

    x = 4
