Q. Solve for all values of a in simplest form.25=∣a+14∣Answer: a=
Understand absolute value equation: Understand the absolute value equation.The equation 25=∣a+14∣ means that the expression inside the absolute value, a+14, can be either 25 or −25, because the absolute value of a number is its distance from zero on the number line, which is always non-negative.
Set up two equations: Set up two separate equations to solve for a. Since the absolute value of a+14 can be either positive or negative 25, we write two equations: 1) a+14=252) a+14=−25
Solve first equation for a: Solve the first equation for a. Subtract 14 from both sides of the equation a+14=25 to isolate a. a+14−14=25−14a=11
Solve second equation for a: Solve the second equation for a. Subtract 14 from both sides of the equation a+14=−25 to isolate a. a+14−14=−25−14a=−39
Write values of a: Write the values of a.We have found two solutions for the equation 25=∣a+14∣, which are a=11 and a=−39.
