Answer 3

To solve the equation 7x = -18, we need to isolate the variable x.

We can do this by performing the following steps:

1. Begin by subtracting 7 from both sides of the equation: 7x - 7 = -18 - 7

   Simplifying the right side: 7x - 7 = -25

2. Next, we want to eliminate the constant term on the left side of the equation. We can achieve this by adding 7 to both sides: 7x - 7 + 7 = -25 + 7

   Simplifying: 7x = -18

3. Finally, we can solve for x by dividing both sides of the equation by 7: (7x) / 7 = (-18) / 7

   Simplifying: x = -18 / 7

   The value of x is approximately -2.5714 (rounded to four decimal places).
