Respuesta :

F= -2 because if u multiply 15 by -2, which gives u -30, u add it to negative 12, since u subtracting a negative, and -12 plus 30 is 18

Answer:

f=−2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−12−15f=18

−12+−15f=18

−15f−12=18

Step 2: Add 12 to both sides.

−15f−12+12=18+12

−15f=30

Step 3: Divide both sides by -15.

−15f/−15 = 30/−15

f=-2
