    6x - 10 = 8

    6x = 18

    x = 3

    Step-by-step explanation:

    6 times a number is 6x because we dont know the number so we assign x to the unknown then multiply by 6. Decreased by 10 simply means subtract 10. "is eight" tells you what the previous is equal to. Now, you add 10 to the - 10 to isolate x on one side of the equation. you are left with 6x = 18 because we added 10 to 8. then you want to get x alone so you divide 6x by 6, and 18 by 6. you get x=3, your answer.

    Answer: The number is 3

    Step-by-step explanation:

    Let the unknown number be a

    6 times a = 6a

    6a - 10 = 8

    We then add 10 to both sides of the equation

    6a - 10 + 10 = 8 + 10

    6a = 18

    Divide both sides of the equation by the coefficient of a that is, 6 we have

    6a/6 = 18/6

    a = 3

    Therefore, the number is 3
