    x=2

    Step-by-step explanation:

    3.8x + 5.2x - 6.7 = 11.3

    Combine like terms

    9x - 6.7 = 11.3

    Add 6.7 to each side

    9x - 6.7+6.7 = 11.3+6.7

    9x = 18

    Divide each side by 9

    9x/9 = 18/9

    x = 2

    Simplify 3.8x + 5.2x - 6.7 to 9x - 6.7

    9x - 6.7 = 11.3

    Add 6.7 to both sides

    9x = 11.3 + 6.7

    Simplify 11.3 + 6.7 to 18

    9x = 18

    Divide both sides by 9

    x = 18/9

    Simplify 18/9 to 2

    x = 2
