Answer 3

To find the roots of the equation, we need to solve for x in the equation -3x - 2 = 19.

Step 1: Get rid of the constant term on the left side by adding 2 to both sides of the equation:

-3x - 2 + 2 = 19 + 2

This simplifies to:

-3x = 21

Step 2: Now, isolate x by dividing both sides by -3:

(-3x) / -3 = 21 / -3

This simplifies to:

x = -7

The root of the equation is x = -7.
