What value of x is in the solution set of 9(2x + 1) < 9x - 182

-21 2⁄9 > x

Step-by-step explanation:

Isolate the variable by dividing each side by factors that do not contain the variable:

2x +1 < x - 20 2⁄9

-2x-2x

1 < -x - 20 2⁄9

+20 2⁄9 20 2⁄9

21 2⁄9 < -x [Divide by -1]

-21 2⁄9 > x [Reverse the inequality symbol whenever you are dividing\multiplying by a negative]
