Q. Solve for all values of b in simplest form.∣∣12b∣∣=9Answer: b=
Understand Absolute Value Definition: We are given the absolute value equation ∣12b∣=9. To solve for b, we need to consider the definition of absolute value, which states that if ∣x∣=a, then x=a or x=−a for a≥0. Since 9 is positive, we can set up two separate equations: 12b=9 and 12b=−9.
Solve for b (Equation 1): Solve the first equation 12b=9. To find b, multiply both sides of the equation by 12.b=9×12b=108
Solve for b (Equation 2): Solve the second equation 12b=−9. Similarly, multiply both sides of this equation by 12.b=−9×12b=−108
Identify Solutions: We have found two solutions for b that satisfy the original equation ∣∣12b∣∣=9. The solutions are b=108 and b=−108. These are the values of b in simplest form.
