    3

    Step-by-step explanation:

    The whole goal is to isolate the variable.

    3x-1=8

    1+3x-1=8+1 first add 1 to both sides of the equation to cancel out the - 1

    3x=9 now just divide 3 to both sides of the equation because the opposite of multiplication is division. So dividing 3 on both sides cancels out the 3 to isolate the x

    3x/3=9/3

    x=3
