Q. Solve for z.−4=∣z∣−9Write your answers as integers or as proper or improper fractions in simplest form.z= _____ or z= _____
Understand and Isolate: Understand the equation and isolate the absolute value.We have the equation –4=∣z∣−9. To isolate the absolute value, we need to add 9 to both sides of the equation.−4+9=∣z∣−9+95=∣z∣
Solve for z:Since ∣z∣=5, z can be either 5 or −5 because the absolute value of both 5 and −5 is 5.So, z=5 or z=−5.
