Q. Solve for all values of x in simplest form.−∣4x−8∣−7=−16Answer: x=
Isolate Absolute Value Expression: Isolate the absolute value expression by adding 7 to both sides of the equation.−∣4x−8∣−7=−16−∣4x−8∣−7+7=−16+7−∣4x−8∣=−9
Divide to Remove Negative Sign: Divide both sides by −1 to get rid of the negative sign in front of the absolute value.−1×−∣4x−8∣=−1×−9∣4x−8∣=9
Set Up Two Equations: Set up two equations to solve for x, because the absolute value of a number can be either positive or negative.4x−8=9 or 4x−8=−9
Solve for x (Equation 1): Solve the first equation for x.4x−8=94x=9+84x=17x=417x=4.25
Solve for x (Equation 2): Solve the second equation for x.4x−8=−94x=−9+84x=−1x=−41x=−0.25
