The solution is x = what

multiply both sides by -2

thank you

To solve the equation -x/2 = 9 for x, you can follow these steps:

1. Multiply both sides of the equation by 2 to get rid of the fraction:
-x/2 * 2 = 9 * 2
This simplifies to: -x = 18

2. To isolate x, multiply both sides of the equation by -1 to change the sign:
-x * -1 = 18 * -1
This simplifies to: x = -18

Therefore, the solution to the equation -x/2 = 9 is x = -18.
