Answer:
x < -3
Explanation:
step 1 - distribute
9(2x + 1) < 9x - 18
18x + 9 < 9x - 18
step 2 - subtract nine x from both sides of the expression
18x + 9 < 9x - 18
18x - 9x + 9 < 9x - 9x - 18
9x + 9 < -18
step 3 - subtract nine from both sides of the expression
9x + 9 < -18
9x + 9 - 9 < -18 - 9
9x < -27
step 4 - divide both sides of the expression by nine
9x < -27
9x/9 < -27/9
x < -3
Therefore, x < -3.
