Answer:
x = -6
Step-by-step explanation:
For this problem, we will use the general expression given by OP in the comments as h(x) = 12 / x to find the value of x that makes this evaluation true, h(x) = -2.
For this, we will simply set the two expressions equal to each other, since they both are h(x), and solve for x.
h(x) = 12 / x
h(x) = -2
h(x) = h(x)
12/x = -2
12/x * x = -2 * x
12 = -2x
12 * (-1/2) = -2x * (-1/2)
-6 = x
Hence, the value of x that makes h(x) = -2, is x = -6.
Cheers.
