No solution

Infinitely many solutions

One solution

Step-by-step explanation:

The first expression:

           -2(3x  - 1) = -6x -1

  Expand the parentheses;

           -6x + 2  = -6x -1

             -6x + (-6x) = -1 -2

                 0 = -3

This problem has no solutions

Second expression:

          2(3x-1) = 6x -2

  Expand the parentheses;

          6x - 2  = 6x -2

           6x -6x = -2 + 2

             0 = 0

This problem has infinitely many solutions

Third expression:

2(3x - 1) = -6x -2

    Expand the parentheses;

       6x -2 = -6x - 2

        6x + 6x = -2 + 2

           12x = 0

               x  = 0

This equation has only one solution

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
