Q. Solve for all values of x in simplest form.9−5∣3−4x∣=−31Answer: x=
Isolate absolute value expression: Isolate the absolute value expression.Add 31 to both sides of the equation to isolate the absolute value term.9−5∣3−4x∣+31=−31+3140−5∣3−4x∣=0Now, divide both sides by −5 to get the absolute value by itself.(40−5∣3−4x∣)/−5=0/−5−8+∣3−4x∣=0
Divide by −5: Isolate the absolute value.Add 8 to both sides of the equation to get the absolute value by itself.-8 + 8 + |3 - 4x| = 0 + 8\(\newline|3 - 4x| = 8\)
Isolate absolute value: Set up two equations to remove the absolute value.Since ∣A∣=B implies A=B or A=−B, we have two cases:Case 1: 3−4x=8Case 2: 3−4x=−8
Set up equations: Solve for x in Case 1.3−4x=8Subtract 3 from both sides.−4x=8−3−4x=5Now, divide by −4 to solve for x.x=5/−4x=−5/4
Solve for x in Case 1: Solve for x in Case 2.3−4x=−8Subtract 3 from both sides.−4x=−8−3−4x=−11Now, divide by −4 to solve for x.x=−11/−4x=11/4
