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
