Answer 2

$|9x + 2| - {3}^{3} = {( - 3)}^{3} \\ |9x + 2| - {3}^{3} + {3}^{3} = 0 \\ |9x + 2| = 0 \\ 9x + 2 = 0 \\ 9x = - 2 \\ x = \frac{ - 2}{9}$
Вроде так.

Answer 3

To solve the equation |9x + 2| - 3³ = (-3)³, follow these steps:

Step 1: Simplify the equation |9x + 2| - 27 = -27

Step 2: Add 27 to both sides of the equation to isolate the absolute value term on the left side. |9x + 2| = 0

Step 3: Since the absolute value of any expression is equal to zero only when the expression inside the absolute value is equal to zero, set 9x + 2 equal to 0 and solve for x. 9x + 2 = 0 9x = -2 x = -2/9

So, the solution to the equation is x = -2/9.
