Q. Solve for all values of x in simplest form.2−5∣7+2x∣=−23Answer: x=
Isolate absolute value expression: Start by isolating the absolute value expression on one side of the equation.We have the equation 2−5∣7+2x∣=−23.Add 5∣7+2x∣ to both sides to move the absolute value expression to one side.2−5∣7+2x∣+5∣7+2x∣=−23+5∣7+2x∣This simplifies to:2=−23+5∣7+2x∣
Add and simplify: Now, subtract 2 from both sides to isolate the term with the absolute value.2−2=−23+5∣7+2x∣−2This simplifies to:0=−25+5∣7+2x∣
Subtract to isolate: Next, add 25 to both sides to solve for the absolute value expression.0+25=−25+25+5∣7+2x∣This simplifies to:25=5∣7+2x∣
Add to solve for absolute value: Divide both sides by 5 to solve for the absolute value of 7+2x.525=55∣7+2x∣This simplifies to:5=∣7+2x∣
Divide to solve for absolute value: Now we have an absolute value equation ∣7+2x∣=5. This means that 7+2x can be either 5 or −5.We will solve for x in both cases.First, let's consider 7+2x=5.Subtract 7 from both sides:7+2x−7=5−7This simplifies to:2x=−2
Consider absolute value equation: Divide both sides by 2 to solve for x.22x=2−2This simplifies to:x=−1
Solve for x (1st case): Now let's consider the second case where 7+2x=−5. Subtract 7 from both sides: 7+2x−7=−5−7 This simplifies to: 2x=−12
Divide to solve for x (1st case): Divide both sides by 2 to solve for x.22x=2−12This simplifies to:x=−6
