Q. Solve for all values of x in simplest form.∣∣5x∣∣=12Answer: x=
Understand absolute value equation: Understand the absolute value equation ∣∣5x∣∣=12. The absolute value of a number is its distance from zero on the number line, regardless of direction. Therefore, the equation ∣∣5x∣∣=12 means that the distance of 5x from zero is 12. This can happen in two ways: either 5x is 12 or 5x is −12.
Set up two equations: Set up two separate equations to solve for x. Since ∣∣5x∣∣=12 can mean 5x is 12 or 5x is −12, we write: 1. 5x=122. 5x=−12
Solve first equation: Solve the first equation (x)/(5)=12.To find x, multiply both sides of the equation by 5:x=12×5x=60
Solve second equation: Solve the second equation (x)/(5)=−12. Similarly, multiply both sides of this equation by 5: x=−12×5x=−60
Combine solutions: Combine the solutions from Step 3 and Step 4.The solutions to the equation ∣∣5x∣∣=12 are x=60 and x=−60.
