Q. Solve for f.∣−3f∣=3Write your answers as integers or as proper or improper fractions in simplest form.f= _____ or f= _____
Understand absolute value equation: Understand the absolute value equation.The equation ∣−3f∣=3 means that the absolute value of −3f is equal to 3. The absolute value of a number is its distance from zero on the number line, which means it is always non-negative. Therefore, −3f can either be 3 or −3.
Set up two equations: Set up two separate equations to solve for f. Since ∣−3f∣ can be either 3 or −3, we set up two equations: −3f=3 and −3f=−3.
Solve first equation: Solve the first equation −3f=3.Divide both sides by −3 to isolate f:f=−33f=−1
Solve second equation: Solve the second equation −3f=−3.Divide both sides by −3 to isolate f:f=−3−3f=1
