Answer 1

Explanation:

Answer 2

x = - 12

Explanation:

9 - 0.5x = 15

* isolate the variable using inverse operations *

step 1 subtract 9 from each side

9 - 9 cancels out

15 - 9 = 6

now we have -0.5x = 6

step 2 divide each side by -0.5

-0.5x / -0.5 = x

6 / -0.5 = - 12

we're left with x = - 12
